Why we need ipv6...
This document provides an introduction and overview of IPv6, including:
- IPv6 is the next generation internet protocol that will replace IPv4, providing a vastly larger address space and additional features.
- The key reasons for adopting IPv6 are that IPv4 addresses are running out due to the exponential growth of internet-connected devices, while IPv6 supports 128-bit addresses providing trillions of times more addresses.
- IPv6 addresses are 128-bit compared to 32-bit IPv4 addresses, written in hexadecimal format divided into eight groups, and features include improved security, mobility, and traffic routing capabilities.
internet protocol version6
IPv6 is the next generation internet protocol that replaces IPv4. It features a 128-bit address space compared to IPv4's 32-bit addresses, allowing for vastly more possible IP addresses. IPv6 was developed in the 1990s in anticipation of IPv4 running out of available addresses. It introduces features like built-in security, auto-configuration, and support for new technologies. IPv6 is now incorporated into modern internet-enabled applications and operating systems.
IPV6 Introduction
This document provides an introduction to IPv6, including an overview of its key features and differences from IPv4. It discusses how IPv6 was developed to address the exhaustion of IPv4 address space and larger routing tables. The core features covered are the new IPv6 header format, its large 128-bit address space, stateless and stateful address configuration, built-in security via IPsec, and improved support for areas like quality of service and network interactions through protocols like Neighbor Discovery.
Why We Need IPv6
Internet Protocol version 6 (IPv6) is the latest version of the
Internet Protocol (IP), the communications protocol that
provides an identification and location system for computers
on networks and routes traffic across the Internet.
IPv4 & IPv6 are not designed to be interoperable, complicating
the transition to IPv6. However, several IPv6 transition
mechanisms have been devised to permit communication
between IPv4 and IPv6 hosts.

The firewall shields the internal corporate network from the internet. A bastion host placed in the firewall's perimeter network examines incoming and outgoing network packets based on their source and destination information in the packet headers. The firewall and its internal router filter packets to only allow approved traffic according to rules, preventing unauthorized access while enabling services like email and file transfers.
Computer networks
The document provides an overview of IPv6 including:
1. IPv6 was developed due to address depletion issues with IPv4 and features a 128-bit address compared to IPv4's 32-bit address, providing vastly more address space and eliminating concerns about future address depletion.
2. The structure of IPv6 addresses is fundamentally different than IPv4 addresses, using eight 16-bit segments.
3. IPv6 packet format includes a base 40-byte header and optional extension headers between the header and payload up to 65,535 bytes in length.
Internet Protocol version 10 (IPv10).
IPv10 is a proposed protocol that allows IPv6 and IPv4 hosts to communicate by putting both IPv6 and IPv4 addresses in the same packet header, denoted IPv10. This addresses issues with IPv4 depletion by enabling continued communication between IPv4-only and IPv6-only hosts. IPv10 introduces efficient inter-version communication, allows indefinite coexistence of IPv4 and IPv6 hosts, and increases the overall available address space. It can be deployed quickly by updating host network cards to support the IPv10 packet format.
Comparative study of IPv4 and IPv6 on Windows and Linux.
This document provides a comparative study of IPv4 and IPv6 performance on Windows and Linux operating systems. It introduces IPv4 and IPv6, compares their key differences, and experimentally measures performance metrics like throughput, delay, jitter and CPU usage for IPv4 and IPv6 on Windows and Linux. The results show that for Windows and Linux, IPv4 generally has higher throughput and lower CPU usage than IPv6. However, IPv6 has advantages like a larger address space and increased security. Linux typically shows the highest CPU usage and TCP throughput for IPv6. The document also reviews several related works comparing IPv4 and IPv6 performance on different operating systems.

Latency i pv4 vs ipv6
The document compares latency between IPv4 and IPv6 networks and explores reasons for differences. It finds that in some cases, IPv6 latency is faster than IPv4 due to a shift in connectivity where IPv6 traffic flows through a tier 1 provider, HE (AS6939), that has higher connectivity in IPv6. The separation of IPv4 and IPv6 networks means latency comparisons do not always reflect an identical network structure. As IPv6 adoption increases, the document predicts the differences between the two networks will decrease.
Journey to IPv6 - A Real-World deployment for Mobiles
This document provides an overview of Telstra's journey to deploying IPv6 for mobiles. It discusses why IPv6 is needed due to growth in devices and traffic, and depletion of IPv4 addresses. It covers the business and technical considerations for transitioning to IPv6. The document outlines Telstra's network architectures for IPv6 including centralised CGN, 464XLAT architecture and addressing schemes. It discusses their deployment model and experiences including growth in IPv6 usage. Lessons learned around community engagement, customer support and reporting metrics are also provided.

1. The host will automatically generate a link-local address starting with fe80::.
2. It will perform duplicate address detection to ensure the address is unique on the local link.
3. If the address is unique, it is assigned to the interface.
4. The host will send a router solicitation to discover network prefixes advertised by routers.
5. Upon receiving a router advertisement with network prefixes, the host will autoconfigure an IPv6 address by combining the prefix with its interface ID.
Network address translation
NAT maps private IP addresses to public IP addresses, allowing multiple devices on a private network to share a single public IP address to access the Internet. It is commonly used when there is a shortage of IPv4 addresses. There are different types of NAT, including dynamic NAT which maps private addresses to public addresses on a need basis, and NAPT which allows thousands of devices to share one IP address by also mapping port numbers. NAT solves issues like merging networks with duplicate private addresses and changing ISPs without renumbering an entire network.
Fast Access to Your Data - Avro, JSON, ORC, and Parquet
The landscape for storing your big data is quite complex, with several competing formats and different implementations of each format. Understanding your use of the data is critical for picking the format. Depending on your use case, the different formats perform very differently. Although you can use a hammer to drive a screw, it isn’t fast or easy to do so.
The use cases that we’ve examined are:
* reading all of the columns
* reading a few of the columns
* filtering using a filter predicate
While previous work has compared the size and speed from Hive, this presentation will present benchmarks from Spark including the new work that radically improves the performance of Spark on ORC. This presentation will also include tips and suggestions to optimize the performance of your application while reading and writing the data.
Finally, the value of having open source benchmarks that are available to all interested parties is hugely important and all of the code is available from Apache.

Building a Smarter Home with Apache NiFi and Spark
This document discusses using Apache NiFi and Spark to build a smarter home. It describes using NiFi on a Raspberry Pi and EC2 to collect sensor data from smart home devices and transmit it to an HDP cluster for storage and analysis with Pig and Spark. It outlines the architecture as a hub-and-spoke model and shows the evolution of the NiFi flows from sequential blocking writes to attribute-based routing. Key discoveries include privacy issues, using MAC addresses to predict arrivals, and motion sensors being less useful alone. Challenges involved Oracle vs OpenJDK, backpressure, and site-to-site configuration.

IPv6 is the newest version of the Internet Protocol that provides a 128-bit addressing system to replace IPv4 and address the problem of looming address exhaustion, featuring a vastly expanded address space, simplified header format, and security improvements to meet future networking needs. It was developed by the IETF and became an internet standard in 2017 to support continued growth of devices connected to the internet by providing trillions of addresses for devices using hexadecimal notation groups separated by colons.
Http Introduction
HTTP is the most popular application protocol on the internet. It uses the client-server model where an HTTP client sends a request to an HTTP server using a request method like GET or POST. The server then returns a response with a status code and can include a message body. A URL identifies a web resource and includes the protocol, hostname, port, and path. HTTP specifications are maintained by the W3C and the current versions are HTTP/1.0 and HTTP/1.1. The HTTP request and response include a start line, headers, and optional body. Common status codes indicate success, redirection, or client/server errors.
Introduction to ipv6 v1.3
The document provides an overview of IPv6 including:
- Limitations of IPv4 that IPv6 addresses such as limited address space and lack of security.
- Key features of IPv6 like a larger 128-bit address space, simpler header format, and built-in security.
- Protocols that support IPv6 functionality like Neighbor Discovery Protocol, Path MTU Discovery, and stateless and stateful address autoconfiguration.

prop-115: Registration of detailed assignment information in whois DB
This proposal suggests registering more detailed IP address assignment information in the WHOIS database to help network operators filter more precisely. It proposes adding port range details for IPv4 addresses and assignment prefix sizes for IPv6 addresses. This would allow operators to filter specific address ranges rather than entire allocations, avoiding over-filtering. The changes may require updating registration rules and database records. Some discussion is needed on user access control and hosting service registrations. The goal is providing information to support responsible filtering while maintaining security and operability.
HyperText Transfer Protocol (HTTP)
HTTP is the application-layer protocol for transmitting hypertext documents across the internet. It works by establishing a TCP connection between an HTTP client, like a web browser, and an HTTP server. The client sends a request to the server using methods like GET or POST. The server responds with a status code and the requested resource. HTTP is stateless, meaning each request is independent and servers do not remember past client interactions. Cookies and caching are techniques used to maintain some state and improve performance.
HTTP Presentation
HTTP/2 is an updated protocol that improves upon HTTP/1.1 by allowing multiple requests to be sent simultaneously over a single TCP connection using multiplexing and header compression. It reduces latency compared to HTTP/1.1 by fixing the head-of-line blocking problem and prioritizing important requests. Key features of HTTP/2 evolved from the SPDY protocol and include multiplexing, header compression, prioritization, and protocol negotiation.

IPV6 INTRODUCTION
This document provides an introduction to IPv6, including an overview of its key features and differences from IPv4. It discusses how IPv6 was developed to address the exhaustion of IPv4 address space and larger routing tables. The summary highlights that IPv6 features a 128-bit address space, stateless and stateful address configuration, built-in security through mandatory IPsec, and more efficient packet routing. Transitioning to IPv6 aims to future-proof internet protocols as network usage grows exponentially.

Overview of IPv6 protocol along with various transition scenarios for the migration from IPv4 to IPv6
IPv6 is the current and future Internet Protocol standard. As anticipated, IPv4 addresses became exhausted around 2012.
The IP address scarcity is the main driver for IPv6 protocol adoption.
IPv6 defines a much larger address space that should be sufficient for the foreseeable future, even taking into account Internet of Things scenarios with zillions of small devices connected to the Internet.
IPv6 is, however, much more than simply an expansion of the address space. IPv6 defines a clean address architecture with globally aggregatable addresses thus reducing routing table sizes in Internet routers.
IPv6 extension headers provide a standard mechanism for stacking protocols such as IP, IPSec, routing headers and upper layer headers such as TCP.
ICMP (Internet Control Message Protocol) is already defined for IPv4. ICMP was totally revamped for IPv6 and as ICMPv6 provides common functions like IP address and prefix assignment.
Lack of business drivers for migrating to IPv6 is responsible for sluggish adoption of IPv6 in carrier and enterprise networks.
Numerous transition mechanisms were developed to ease the transition from IPv4 to IPv6. Many of these mechanisms are complex and difficult to administer.
The transition mechanisms can be coarsely classified into dual-stack, tunneling and translation mechanisms.

I pv4 vs ipv6
IPv4 and IPv6 are different versions of the Internet Protocol. IPv4 uses 32-bit addresses which limits the available number of addresses to around 4 billion, while IPv6 uses 128-bit addresses allowing for a vast number of available addresses. Some techniques were used to extend IPv4 such as subnetting and NAT, but IPv6 was developed to provide a long-term solution and overcome IPv4's scaling limitations. IPv6 improves upon IPv4 in areas such as efficiency, security, auto-configuration, and header structure. Widespread adoption of IPv6 has been slowed due to compatibility issues and costs of upgrading systems.
Internet protocol v6
IPv6 was developed to address the impending exhaustion of IPv4 addresses. It uses 128-bit addresses compared to IPv4's 32-bit addresses, providing vastly more unique addresses. IPv6 simplifies address assignment, network renumbering, and router announcements. It also implements additional features like improved security via IPsec. While the transition to IPv6 presents challenges, it is necessary to support future internet growth given IPv4's limited address space.

This document provides information about the CS352 course on Internetworking Protocols. It discusses the topics that will be covered in Unit III, including IPv6 transition issues, IPsec, addressing, extension headers, routing, autoconfiguration, and more. It lists the course instructor and their details. It then provides background on problems with IPv4 and advantages of IPv6. Several sections define IPv6 headers and addressing, describing the fixed header, extension headers, address notation, and network/node addressing splits.
Internet Protocol Version 6 By Suvo 2002
IPv6 is the next-generation Internet protocol that replaces IPv4. It features a 128-bit address size allowing for many more IP addresses compared to IPv4's 32-bit addresses. IPv6 also includes improvements in routing, network autoconfiguration, security, quality of service, and extensibility. A transition from IPv4 to IPv6 is underway using mechanisms like dual stacking that allow both protocols to coexist on networks. While not yet widely deployed, IPv6 is expected to fully replace IPv4 in the coming years.
IPv6.pptx
IPv6 was created as a replacement for IPv4 to address its shortcomings like limited address space. IPv6 uses 128-bit addresses compared to 32-bit in IPv4, allowing for a vastly larger number of available addresses. It was designed with features like auto-configuration, IPsec security, prioritization support, and mobility in mind. The IPv6 header was also simplified compared to IPv4 to enable faster routing while still providing necessary routing information.
Compatibility between IPv4 and IPv6
IPv4 addresses are running out, so IPv6 was created with a vastly larger 128-bit address space. During the transition, IPv4 and IPv6 will coexist via three main methods: dual-stack, tunneling, and translation. For internet service providers, dual-stack is the best approach as it allows gradual migration while both protocols are supported. The presentation provides details on IPv4 and IPv6 addressing schemes, transition mechanisms, and configuration examples for tunneling dual-stack implementations at an ISP.

This document provides an overview of Internet Protocol version 6 (IPv6). It discusses some of the key features and advantages of IPv6, including its larger 128-bit address space that supports up to 3.4×1038 addresses compared to the 4.3 billion addresses supported by IPv4. The document also compares IPv6 to IPv4, noting they are not interoperable but that most transport and application protocols can operate over both with little change. Transition mechanisms have been developed to allow communication between IPv4 and IPv6 networks.
Implementation of “Traslator Strategy” For Migration of Ipv4 to Ipv6
This paper is focused on the Translator strategy for migration of IPv4 to Ipv6 implemented in Cisco packet
tracer. It describes the design and configuration of network devices and packet transfer between devices of IPv4
and IPv6 networks using NAT-PT as transition mechanism. First major version of IP, IPv4 is the dominant
protocol of internet.IPv6 is developed to deal with long anticipated problem of IPv4 running out of addresses.
The migration from IPv4 to IPv6 must be implemented node by node by using auto-configuration procedures to
eliminate the need to configure IPv6 hosts manually.

Solution
Introductory lines:
The internet protocol or IP specifies and describes the technical details and formats of fragments
of data (Also known as packets.) along with addressing schemes (numerical; actually in binary
but can be interpreted as decimals or hexadecimals assigned to each of the devices connected
through the network) in order to uniquely identify them and create a platform for secure and
reliable communication.
Ipv4 over the years was proved and deployed for communications over the internet. However in
the current days it becomes obsolete and deficient in order to serve the huge and increasing
number of users or network devices.
To make this possible, the IPv6 comes into existence. The IPv6 provides many extra features and
claims to support and serve this increasing number of devices for upcoming coming centuries.
Let’s discuss about the similar and distinct features of both IPv4 and IPv6.
IPv4 in terms of IP addresses, Address allocation, masks and types:
IPv6 in terms of IP addresses, Address allocation, masks and types:
IPv4 in terms of IP header:
Headers in IPv4 are of variable length that varies from 20 to 60 bytes.
IPv4 does not identify packet flow for QOS handling.
It adds checksum filed for identification of transmission errors in the data.
IPv6 in terms of IP header:
Uses fixed length of 40 bytes of headers and there is no concept of option filed in header.
It supports packet flow for QOS by flow level filed.
IPv6 does not implements checksum for error handling.
IPv4 in terms of IP packets ports and security:
IPv4 supports the packet size of 576 bytes.
They also support packet filtering mechanisms through firewalls.
IPv4 supports for port spaces of the range 1 to 65535
IPsec in IPv4 is optional.
IPv6 in terms of IP packets ports and security:
IPv6 supports the packet size of 1280 bytes.
They does not supports packet filtering mechanisms.
The way the portts work both in IPv4 and IPv6 are the same.
IPv6 has inbuilt IPsec support.
IPv4 was successful;;y deployed in 1981 over internet whereas IPv6 was planned to be deployed
from 1999 but could partially deployed till the date.
Why transition from IPv4 to IPv6 must occur ?
The deficiency of IP address of IPv4 type is one of the most eye catching reasons for transition
towards IPv6. Each and every day the Internet is experiencing phenomenal increase of devices
which are being connected and using the internet.
In order to provide services to all the address space of IPv4 seems to be fewer. Hence
a transition from IPv4 to IPv6 is must needed to satisfy such demand of larger address space.
Except this, the other technical features like improve.
i pv6
The document discusses IPv6, the next generation Internet Protocol. It introduces IPv6 and describes some key differences from IPv4, including a much larger 128-bit address space compared to 32-bits in IPv4. It also describes some advantages IPv6 has over IPv4 such as built-in support for multicasting and stateless address autoconfiguration. The document outlines various mechanisms for transitioning from IPv4 to IPv6, including dual stack implementations, tunneling protocols, and translation technologies.
IPV6 EXPLANATION BY FOROUZANN DATA COMMUNICATION
IPv6 addresses are 128 bits long compared to 32 bits for IPv4, solving the problem of IPv4 address depletion. IPv6 addresses are written in colon hexadecimal format and can be abbreviated by omitting leading zeros and replacing consecutive sections of all-zeroes with "::". The IPv6 packet format includes a fixed-length 40-byte header and optional extension headers that provide additional functionality compared to IPv4 options. During the transition from IPv4 to IPv6, devices will have both protocol stacks and query DNS to determine which version to use for a given destination.
RASHMI VT REPORT
This document provides a report on a vocational training in IPV6 that was completed by Rashmi Kumari. It includes an introduction to IPV6 that compares it to IPV4 and highlights its larger address space, built-in multicasting, and network layer security. It also details IPV6's simplified packet format and routing. The report then discusses addressing, OSPF, implementing OSPF for IPV6, and building a simulated network with dual stack transition in GNS3 to test IPV6 functionality.
Comparative study of IPv4 & IPv6 Point to Point Architecture on various OS pl...
This document provides a summary of a comparative study on the performance of IPv4 and IPv6 protocols under different operating systems. The study analyzed bandwidth utilization, round trip time, and overhead for IPv4 and IPv6 in point-to-point configurations under Windows 2007, Mac OS, and Red Hat Linux. Experiments were conducted between 3 PCs configured for IPv4 and IPv6 communications over an unloaded network with 3 routers and 3 workstations. Key differences between IPv4 and IPv6 such as address length, header fields, and transition mechanisms are also outlined.
DCN 5th ed. slides ch22 Next Generation IP.pdf
IPv6 was created to replace IPv4 due to IPv4's limited address space. IPv6 uses a 128-bit address compared to IPv4's 32-bit address, providing vastly more unique IP addresses. It also features improvements like better support for extensions and more robust security features. The document discusses IPv6 addressing formats, allocation of address blocks, stateless autoconfiguration, renumbering, packet header format, and the roles of extension headers. It provides technical details on how IPv6 aims to resolve limitations in IPv4 and support future networking needs.
Ip v4 & ip v6
IPv4 is the current version of the Internet Protocol but has limitations including a limited 32-bit address space that is nearly depleted, lacking built-in network security, and limited quality of service capabilities. IPv6 was developed to address these issues by using a larger 128-bit address space to avoid scarcity, incorporating IPsec to provide security, and improving quality of service and auto-configuration features. While IPv6 adoption is still growing, transitioning networks to be dual-stacked with both IPv4 and IPv6 ensures compatibility and avoids missing traffic from users on IPv6-only networks.
