The document discusses Address Resolution Protocol (ARP), which allows a machine on a network to dynamically map logical IP addresses to physical hardware addresses. It describes how ARP works by broadcasting a request packet to find the physical address associated with a target IP address. The target machine then responds with its physical address in an ARP reply message. The original sender can then directly address packets to the target using its physical address. The document outlines the ARP packet format and encapsulation process, as well as the basic steps of how ARP operates to perform dynamic address mapping on a network.
This ppt contains what is dhcp, it's need, advantages, disadvantages, IP address assignment process and types, DHCP architecture and lastly some differences.
How do we get datagrams to the right physical host?
Tricky part comes when a router is forwarding to a LAN with multiple hosts (which is typically the case)
IP datagrams contain an IP address
Configured in OS
NIC’s only understand addressing of their particular network
Ethernet’s 48 bit MAC addresses

Generating a custom Ruby SDK for your web service or Rails API using Smithyg2nightmarescribd
Have you ever wanted a Ruby client API to communicate with your web service? Smithy is a protocol-agnostic language for defining services and SDKs. Smithy Ruby is an implementation of Smithy that generates a Ruby SDK using a Smithy model. In this talk, we will explore Smithy and Smithy Ruby to learn how to generate custom feature-rich SDKs that can communicate with any web service, such as a Rails JSON API.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

3. Address Mapping
• Static Mapping
– Static mapping means creating a table that associates a logical
address with a physical address This table is stored in each
machine on the network
– This has some limitations because physical addresses may
change static mapping table must be updated periodically
This overhead could affect network performance.
• Dynamic Mapping
– In dynamic mapping, each time a machine knows the logical
address of another machine, it can use a protocol to find the
physical address
• Address Resolution Protocol (ARP) : logical address
physical
address
• Reverse Address Resolution Protocol (RARP): physical address
logical address It is replaced by BOOTP dan DHCP

The sender knows the IP address of the target
IP asks ARP to create an ARP request message, filling in the sender physical
address, the sender IP address, and the target IP address. The target physical
address field is filled with 0s.
The message is passed to the data link layer where it is encapsulated in a
frame using the physical address of the sender as the source address and the
physical broadcast address as the destination address.
Every host or router receives the frame. Because the frame contains a
broadcast destination address, all stations remove the message and pass it to
ARP. All machines except the one targeted drop the packet. The target
machine recognizes the IP address.
The target machine replies with an ARP reply message that contains its
physical address. The message is unicast.
The sender receives the reply message. It now knows the physical address of
the target machine.
The IP datagram, which carries data for the target machine, is now
encapsulated in a frame and is unicast to the destination.

13. Proxy ARP
• A technique to create a subnetting effect.
• A proxy ARP is an ARP that acts on behalf of a
set of hosts
• Whenever a router running a proxy ARP
receives an ARP request looking for the IP
address of one of these hosts, the router sends
an ARP reply announcing its own hardware
(physical) address
• After the router receives the actual IP packet, it
sends the packet to the appropriate host or
router
