Address Resolution Protocol - Wikipedia
The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite. ARP was defined in 1982 by RFC 826, which is Internet Standard STD 37.

2020年8月29日 · ARP协议的基本功能是使用目标主机的IP地址，查询其对应的MAC地址，以保证底层链路上数据包通信的进行。 为了实现在网络接口物理地址与IP地址间的转换，ARP协议中引入了ARP缓存表的概念。 ARP缓存表中记录了一条一条的<IP地址，MAC地址>对，他们是主机最近运行获得的关于周围其他主机的IP地址到物理地址的绑定，当需要发送IP数据包时，ARP层根据目的IP地址来查找ARP缓存表，并将匹配的MAC地址装入以太网帧首部，最后发送以太网数据 …
ARP Protocol Packet Format - GeeksforGeeks
2023年2月16日 · ARP Packet Format. The ARP packet format is used for ARP requests and replies and consists of multiple fields including hardware type, protocol type, hardware and protocol size, operation, sender and target hardware, and IP addresses. These fields work together to help devices on a network find and communicate with each other.
How Address Resolution Protocol (ARP) Works? - GeeksforGeeks
2024年9月27日 · The acronym ARP stands for Address Resolution Protocol which is one of the most important protocols of the Data link layer in the OSI model. It is responsible to find the hardware address of a host from a known IP address. There are three basic ARP terms.
Traditional ARP – Address Resolution Protocol - Practical …
As we’ve learned before, the Address Resolution Protocol (ARP) is the process by which a known L3 address is mapped to an unknown L2 address. The purpose for creating such a mapping is so a packet’s L2 header can be properly populated to deliver a packet to the next NIC in the path between two end points.
ARP (Address Resolution Protocol) explained - NetworkLessons.com
This lesson explains Address Resolution Protocol (ARP) to you. Network devices use ARP to find the MAC address of the IP address they want to reach.
Fundamentals of ARP - Address Resolution Protocol - Cisco …
PC-1 will now send an ARP request to find the MAC address of its gateway, so that it can complete the frame and eject it out of its Ethernet interface. Step 1. The frame is lacking the destination MAC address information. Step 2. So the PC-1 will send a ARP request inquiring the MAC address of the configured gateway
Address Resolution Protocol (ARP) Each Ethernet frame carries a destination MAC address and a source MAC address. Once IP layer has determined the next-hop destination IP address (which may be a router or the final destination of the datagram-in any case, it is where the datagram will go next), the link layer has to
The TCP/IP Guide - ARP Message Format
ARP messages use a relatively simple format. It includes a field describing the type of message (its operational code or opcode) and information on both layer two and layer three addresses. In order to support addresses that may be of varying length, the format specifies the type of protocol used at both layer two and layer three and the length ...
