What does dhcp mean?
dhcp, the dynamic host setting protocol, is a LAN network protocol that uses the UDP protocol. The main purpose is to quickly and automatically assign IP addresses to the network. DHCP can help us assign IP addresses and related IP information to computers in the network.
dhcp can also configure the correct subnet mask, default gateway and DNS server information on the device. Because of these capabilities, almost every device connected to the network is now configured with DHCP.
DHCP is usually used in large-scale local area network environments. Its main function is to centrally manage and allocate IP addresses, so that hosts in the network environment can dynamically obtain IP addresses, Gateway addresses, DNS server addresses and other information. And can improve the utilization rate of addresses.
dhcp has the following four functions:
1. Ensure that any IP address can only be used by one DHCP client at the same time.
2. DHCP should be able to assign permanent fixed IP addresses to users.
3. DHCP should be able to coexist with hosts that use other methods to obtain IP addresses (such as hosts with manually configured IP addresses).
4. The DHCP server should provide services to existing BOOTP clients.
DHPC works by "renting" IP addresses and IP information to network clients for a period of time. Therefore, the DHCP client must interact with the DHCP server through a series of DHCP messages, mainly including DHCP DISCOVER, DHCP OFFER, DHCP REQUEST and DHCP ACK.
