How to configure the DHCP service in Windows system

First, DHCP overview

(1) Understanding of DHCP services

DHCP (Dynamic Host Configuration Protocol) is a protocol developed by the IETF (Internet Task Force) designed to automatically assign TCP/IP parameters to computers in a TCP/IP network

DHCP provides secure, reliable, and simple TCP/IP network settings that reduce the burden of configuring IP addresses

(2), the good outside of DHCP

Reduces the workload of the Administrator

Avoid the possibility of input errors

Avoid IP conflicts

When the network changes the IP address segment, you do not need to reconfigure each user's IP address

Increased utilization of IP addresses

Client-friendly configuration

Second, the working principle of DHCP

(1), DHCP distribution mode

Auto-assign (Automatic allocation): This is the permanent use of this IP address when a DHCP client successfully obtains an IP address from a DHCP server for the first time

Manual assignment: The IP address is specifically assigned by the DHCP server administrator

Dynamic allocation: Is when a DHCP client first obtains an IP address from a DHCP server and does not use the address permanently, and after each use, the DHCP client needs to release the IP address so that other clients can use

(2), DHCP lease process

Client requests IP (client sends DHCP Discover broadcast packet)

Server response (server sends DHCP offer broadcast package)
Client chooses anti-IP (client sends DHCP request broadcast packet)

Server determines lease (server sends DHCP ACK broadcast packet)

1, client request IP

2, server response
