IP Configuration
An IP address is a numerical label assigned to devices in a network using the Internet Protocol for communication. It is composed of four numbers separated by periods, with each number representing eight bits for a total of 32 bits. A subnet mask defines which parts of the IP address represent the network ID and which represent the host ID. A default gateway, usually a router, delivers packets when a computer does not know the destination network.
IP and MAC Address
IP addresses are unique identification numbers given to devices to connect to the internet. There are two main types: IPv4 and IPv6. IPv4 addresses are 32-bit and are divided into 5 classes - A, B, C, D and E - with different network and host address ranges. MAC addresses are 48-bit unique hardware numbers embedded in network cards during manufacturing that serve as the physical address of network devices.

IP Addressing & subnetting strategy
The document discusses the Internet Protocol (IP) which is the cornerstone of the TCP/IP architecture and allows all computers on the Internet to communicate. There are two main versions of IP - IPv4, the currently used version, and IPv6 which is intended to replace IPv4 and includes improvements like longer addresses. IP addresses are 32-bit for IPv4 and 128-bit for IPv6. Strategies like private addressing and Classless Inter-Domain Routing (CIDR) help conserve the limited number of available IP addresses.

This document discusses IP addressing and network classes. It explains that an IP address has 32 bits divided into four octets written in dotted decimal notation. It also describes MAC addresses which identify network interfaces and are unique, but cannot efficiently route traffic like IP addresses. The document outlines the different network classes (A, B, C, D), their address ranges, and typical uses.
Ip addressing
IP addressing provides a unique identifier for devices on a network. There are two main types - static and dynamic. IP addresses are 32-bit numbers divided into network and host portions. Classes A, B, and C determine the portions. Subnetting and CIDR allow flexible allocation. Special addresses like private and link-local are never used publicly. IPv6 uses 128-bit addressing. Tools like ping, tracert, and pathping test network connectivity. Mobile IP uses home and care-of addresses to maintain connectivity as devices move between networks, with home and foreign agents facilitating address changes. Inefficiency can occur via double crossing or triangle routing.

Report on ip addresses
IP is the protocol that handles addressing and routing of data across the internet. Each device connected to the internet has a unique IP address that is used to identify it and route data to it. There are different classes of IP addresses that determine the number of devices that can be connected to a network. IP addresses are represented numerically in dot-decimal notation and newer versions of IP have expanded the available address space to meet growing internet demands.
Addressing
Addressing deals with uniquely identifying the location of an entity for communication purposes. It involves a name/identifier, address, and route. Addresses allow messages to be delivered to the intended destination. IP addresses in IPv4 are 32-bit numbers that identify devices on the network. IPv6 was developed to replace IPv4 and uses 128-bit addresses to overcome the address space limitations of IPv4. A transition approach is needed to integrate IPv6 since the internet cannot be abruptly changed over.

Cn ipv4 addressing
IPv4 addresses are 32-bit numbers that uniquely identify devices on the internet. They are divided into four octets and can identify both a device and its network. There are different classes of IP addresses based on the value of the first octet, with Class A having up to 127 networks and over 16 million hosts each, Class B having 16,000 networks with 65,000 hosts each, and Class C having over 2 million networks with 254 hosts each. IP addresses use a hierarchical structure to organize networks and subnetworks.
Ipv6
This document discusses IPv6 addressing and how it differs from IPv4 addressing. Some key points:
- IPv6 addresses are 128 bits long compared to 32 bits for IPv4, represented by 8 groups of 4 hexadecimal digits separated by colons.
- IPv6 address space is huge, with 2^128 possible addresses compared to 2^32 for IPv4.
- IPv6 addresses support zero compression where consecutive fields of zeros can be represented by double colon.
- Common IPv6 addresses include loopback of ::1, unspecified address of ::, and site-local and link-local addresses have specific prefixes.
NET+ Subnetting
Subnetting is the process of taking one IP network address and dividing it into two or more sub-networks to create smaller network segments. It is done to add more local area networks, free up bandwidth, and localize departments. An IP address is made up of 32 bits divided into four octets, and subnetting works by splitting the address into a network and host portion to establish multiple sub-networks.
TCP IP Addressing
The document discusses TCP/IP addressing and related concepts. It introduces TCP/IP and its layered architecture, with a focus on addressing at the network, transport, and physical layers. It describes IP address classes and subnetting as ways to allocate addresses and networks, and how CIDR and variable length subnet masking improved on these methods.

Computer Networking: Internet Protcol (IP) and IP Addressing
IP specifies the format of packets and uses an addressing scheme to route them. It provides an unreliable connectionless service. Most networks use IP with TCP, which establishes a virtual connection and provides reliable delivery between hosts. IP addresses identify both the network and specific host device. Subnet masks divide IP addresses to represent the network and host portions. Classful addressing is now replaced with classless addressing which allows variable length subnet masks.
Addressing in networking (IP,MAC,Port addressing)
This document discusses IP addressing, MAC addressing, and port addressing. IP addressing assigns logical addresses to devices using a hierarchical numbering scheme. Addresses can be static, assigned manually, or dynamic, assigned automatically by a DHCP server. MAC addresses are unique hardware addresses that identify each node on a network. Port addressing refers to the logical port numbers applications use to share network resources simultaneously on the same computer.
Ip address
IP addresses are 32-bit numbers that uniquely identify devices on a network. They allow for file transfers and email communication using the Internet Protocol. There are five classes of IP addresses - A, B, C, D, and E - which are divided into ranges to define large, medium, and small networks. Users can determine the IP address of their own device or other computers and websites using commands like ipconfig and ping.
Computer network
IPv4 addresses are 32-bit numbers that uniquely identify devices connected to the internet. The total address space consists of over 4 billion possible addresses. Addresses are divided into classes based on the bits in the first octet, with classes A, B, and C used for general IP addressing and classes D and E reserved for other uses. Subnetting allows a single class A or B address to be divided into multiple subnets to create more networks, while supernetting combines multiple class C addresses into a larger supernetwork to create a mid-sized block of addresses.
Ip addressing classful
This document discusses IP addressing and classful addressing in TCP/IP networking. It covers the following key points:
- IP addresses are 32-bit addresses that uniquely identify devices on the Internet. They are organized into classes A, B, C, D and E based on the binary pattern of the address.
- Classful addressing allocates address blocks to organizations based on these classes. However, this led to inefficient address usage and rapid depletion of available addresses.
- Subnetting and supernetting were introduced to allow better allocation of addresses within the original classful blocks through the use of subnet and supernet masks. However, classful addressing is now mostly obsolete.
Ip address classes
Class A IP addresses have the format N.H.H.H and support up to 126 networks with over 16 million hosts per network. Class B addresses are N.N.H.H, allowing for over 16,000 networks with nearly 65,000 hosts each. Class C IP addresses use the N.N.N.H format for over 2 million networks of 254 hosts apiece.
Ip address and subnetting
IP addressing and subnetting allows networks to be logically organized and divided. The key objectives covered include explaining IP address classes, configuring addresses, subnetting networks, and advanced concepts like CIDR, summarization, and VLSM. Transitioning to IPv6 is also discussed as a way to address the depletion of IPv4 addresses and improve security.
IP Address
The document discusses IP addresses and IPv6 addresses. It provides information on the structure of IP addresses, subnetting, CIDR notation, and IPv6 addressing. Some key points include:
- An IP address identifies a device on a network and has two parts - a network prefix and host number. Subnetting splits the host number into a subnet number and smaller host number.
- CIDR notation specifies the length of the network prefix to efficiently allocate address space. IPv6 addresses are 128-bit for a huge number of available addresses compared to IPv4.
- IPv6 introduces new address types like multicast for groups and anycast to select one group member. Provider-based addressing allocates IPv6
IPv4 Addressing
This document discusses the Internet Protocol (IP) version 4 and 6. It describes the key tasks of IP including addressing computers and fragmenting packets. IP version 4 uses 32-bit addresses while IP version 6 uses 128-bit addresses and has improvements like larger address space and better security. The document also covers IP address classes, private addressing, subnetting, Classless Inter-Domain Routing (CIDR), and address blocks.
Basics of IP Addressing
This document provides an introduction to IP addressing, including:
- A brief history of IP development and the OSI and TCP/IP models.
- An overview of IP address classes (A, B, C, D, E), how they are determined, and their characteristics like address ranges and network/host portions.
- Explanations of limitations of classful addressing, subnetting, and how classless or CIDR addressing helps address those limitations by allowing flexible prefix lengths.
- An example is given of how CIDR allows efficient allocation of addresses to networks of different sizes.
Ip Addressing Basics
The document discusses IP addressing basics including MAC addresses, IP addresses, private and public IP addresses, and subnetting. It provides examples of MAC addresses, ifconfig output showing MAC and IP addresses, private IP address ranges, and how to break up a Class C network into multiple subnets using subnet masks.
ip addressing & routing
The IP addresses used to identify systems on a TCP/IP network. The IP address is an absolute identifier of both the individual machine and the network on which it resides.
Every IP datagram packet transmitted over a TCP/IP network contains the IP addresses of the source system that generated it and the destination system for which it’s intended in its IP header.
IP_ADDRESSING_AND_SUBNETTING.pptx
The Internet Protocol (IP) is the foundational protocol of the TCP/IP architecture that all computers on the Internet use to communicate. There are two main versions of IP - IPv4, the currently used version, and IPv6 which is intended to replace IPv4. An IP address uniquely identifies a device on the network and consists of a network portion and host portion. IP allows for fragmentation of packets but does not guarantee delivery. Subnetting allows a single network to be divided into multiple logical subnets to improve routing and management.
https://diplomasolutionstudents.blogspot.com/
The document discusses network layer protocols and IP addressing. It covers the functions of the network layer including routing, logical addressing, internetworking, and fragmentation. It then describes IP addressing, including address space, notations like binary, dotted decimal, and hexadecimal. It explains classful addressing and how addresses are divided into network ID and host ID for classes A, B, and C. Class A uses 8-bit network IDs and 24-bit host IDs, class B uses 16-bit network IDs and 16-bit host IDs, and class C uses 24-bit network IDs and 8-bit host IDs. Rules for assigning network IDs and host IDs are also provided.

IP & MAC Addressing
IP and MAC addresses are unique identifiers for devices connected to a network or the internet.
An IP address identifies a device and allows information to be sent between devices, while a MAC address specifically identifies the device's network interface card. IP addresses contain both a network ID and host ID to identify the network segment and individual device. There are two main versions of IP - IPv4 uses 32-bit addresses and IPv6 uses 128-bit addresses. IP addresses are classified into five categories - Classes A, B, C, D and E - which determine how many bits are used for the network vs host portions.

Ip addressing
IP addresses are a unique identifier for devices connected to a network. They allow for the delivery of data packets across networks. The structure of IP addresses includes a network prefix that identifies the network and a host number that identifies the specific device. Techniques like subnetting, CIDR, and IPv6 were developed to address the limited available IPv4 address space and allow for more efficient allocation and routing of IP addresses.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

An improved modulation technique suitable for a three level flying capacitor ...
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.
Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Dcn class a subnetting
- 1. Class A Subnetting Presentation By: Debendra Adhikari
- 2. Overview: - Network and Internet - IP Addressing - Class Addressing - Subnetting Concept - Class B Subnetting
- 3. Network: -a collection of interconnected hosts, via some shared media which can be wired or wireless. Example : Two PC’s connected via wire. Internet : - a global system of interconnected computer networks. - Uses protocols to link devices worldwide for communication and exchange.
- 4. Components of Network - Host - Media - Hub - Switch - Router - Gateways - Firewalls
- 6. IP Addressing - a logical address is given to all hosts connected to Internet and this logical address is called Internet Protocol Address. - a majority of the internet uses a protocol suite called the Internet Protocol Suite also known as the TCP/IP protocol suite.
- 7. An IP address, which is 32-bits in length, is divided into two or three parts as depicted:
- 8. Class Addressing ● Class A - it uses first octet for network addresses and last three octets for host addressing ● Class B - it uses first two octets for network addresses and last two for host addressing ● Class C - it uses first three octets for network addresses and last one for host addressing ● Class D - it provides flat IP addressing scheme in contrast to hierarchical structure for above three. ● Class E - It is used as experimental.
- 9. Subnetting: - a logical subdivision of an IP network. Subnet Masking: The 32-bit IP address that contains information about the host and its network.
- 10. Class A Subnetting In Class A, only the first octet is used as Network identifier and rest of three octets are used to be assigned to Hosts. (i.e. 16777214 Hosts per Network) Default subnet mask of class A is 255.0.0.0
- 11. Borrowing Bits - Key concept in subnetting is borrowing bits from host portion of network to make subnetwork. - Rules govern this borrowing,involves ensuring that some bits are left for a Host ID
- 15. Thanks for Hearing !!!!!
