When a system with a local disk is booted, the IP address is generally read from the configuration file on the disk. However, diskless machines, such as X terminals or diskless workstations, need to use other methods to obtain the IP address.Each system on the network has a unique hardware address, which is configured by the network interface manufacturer. The RARP implementation process of a diskless System reads the unique hardware address from the

The RARP protocol is opposite to the ARP protocol. We will also present the specific rules here. We hope to make a comparison with the ARP Protocol process, which will certainly help you. The ARP protocol we just introduced is to find the physical address by querying the network. The RARP protocol we will discuss next is the opposite: it gets its IP address by querying other hosts on the network.. Usually,

corresponding hardware address); Received ARP reply, before that IP data can be sent; 2.3 ARP cache for storage and formatLike DNS, ARP works by mapping, in effect a key is a map of the IP address. and DNS at different levels have their own cache and TTL, each host has its own ARP cache, the survival time is generally 20 minutes .ARP command query to cache entryAddress HWtype HWaddress Flags Mask Iface192.168.43.1 ether 0c:1d:af:d6:a

RARP: Reverse address Translation protocol. And a protocol that converts physical addresses to IP addresses, working at the network level. The basic working principle of RARP is as follows: (1) The sender sends a local RARP broadcast packet, declares its own MAC address in this broadcast packet, and requests any RARP

types, which are ARP requests (value 1), ARP Reply (value 2 ), the RARP request (value 3), and the RARP answer (value 4) The next four fields are the hardware address of the sending side (in this case, the Ethernet address), the Protocol address (IP address) of the sending side, the hardware address of the destination end The protocol address of the client and destination .

address of the end to the mapping table, so that later and its communication will not need to make ARP requests, such as:RARP protocolContrary to the purpose of the RARP protocol and the ARP protocol, it is only known that the host with its own hardware address can find its IP address through the RARP protocol. The packet format of RARP is basically consistent w

The Reverse Address Translation protocol (Rarp:reverse addressing Resolution Protocol) Reverse Address Translation Protocol (RARP) allows the physical machine on the LAN to request its IP address from the Gateway server's ARP table or cache. The network administrator creates a table in the LAN gateway router to map the physical address (MAC) and its corresponding IP address. When a new machine is set up, its RARP
