In our previous studies on network protocols, we found that some references are explained by combining the BOOTP protocol, DHCP protocol, and DHCP server. So what is the relationship between DHCP and BOOTP? BOOTP relay proxy BOOTP (Bootstrap Protocol) relay proxy is an Inter

In the previous article, we learned about the BOOTP protocol. Here we will mainly explain some content and relationships between dhcp bootp. Hope to help you.

The bootstrap protocol (BOOTP) is a host configuration protocol developed prior to DHCP and is mainly used in diskless workstation networks. The DHCP protocol is improved on the basis of BOOTP and eliminates the special limitations of

BOOTP is short for the Bootstrap Protocol, and DHCP is short for the Dynamic Host Configuration Protocol. As the same as the Host Configuration Protocol, BOOTP first appeared, and DHCP was improved based on it, and fixed so
Network Protocol-BOOTP protocol
Note: BOOTP stands for Bootstrap Protocol. BOOTP is a TCP/IP-based Protocol that allows diskless sites to obtain IP addresses from a central server, assign a dynamic IP address to the diskless workstation in the LAN. You do not need to set a static IP address for each user. When using th
Currently, the IP address assignment of routers mainly includes DHCP and BOOTP, which are also the Dynamic Host Allocation Protocol. Its predecessor is BOOTP. BOOTP was originally used on a network without a disk host connection, the following describes the differences between the two methods.

The detailed Protocol content is included in RFC documents rfc2131 and rfc1541.

performing load balancing, You need to analyze some specific fields based on different user needs and then forward them to different servers. Therefore, we need to focus on resolving the DHCP packet format.
2. DHCP packet format
DHCP is an extension of the BOOTP protocol. The data packet formats of the two are the same. Some fields in the packet are used for BOOTP.
