Dynamic Host Configuration Protocol (DHCP) is a network protocol that allows a server to automatically assign an IP address to a computer from a defined range of numbers (i.e. i.e. a scope) configured for a given network. Why is DHCP important? DHCP allows you to manage networks' IP address scopes and other TCP/IP settings such as DNS, default gateway in the DHCP server.Say no to plagiarism.

DHCP client software sends a DHCP broadcast request requesting the necessary information each time a computer or device connects to the network. Any DHCP server on the network can respond to the request. The DHCP server manages a pool of IP addresses as well as information about client configuration settings such as default gateway, domain name, nameservers. Upon receiving a DHCP request, the DHCP server can respond with specific information for each client, as configured by an administrator, or with a specific address and any other information valid for the entire network and for the period for which the allocation is valid. A DHCP client typically requests this information immediately after startup, and periodically thereafter before the information expires. A DHCP client will request the same parameter values ​​when an assignment is refreshed. However, the DHCP server can assign a new IP address based on the assignment policies set by administrators. The server must be configured with a scope before a DHCP server can provide IP addresses to clients. The extent of an IP address range can be leased to DHCP clients on a subnet. In addition to IP addresses, a scope can also assign optional parameters to DHCP clients, including the IP address of DNS servers, WINS servers and routers, etc. Once a scope has been created, it appears in the DHCP tab. Every DHCP server requires at least one active scope to operate on a network. If you only have a few IP addresses, you may need to reserve more IP addresses for high-priority users. That's why we need to exclude the IP address to reserve the IP address for priority users, while the range outside the excluded IP address will be assigned to normal users. A network administrator reserves a range of IP addresses for DHCP, and each DHCP client on the local network is configured to request an IP address from the DHCP server during network initialization. This request and grant process uses a lease concept with a controllable time period, allowing the DHCP server to retrieve and then reassign IP addresses that are not renewed. Keep in mind: this is just an example.

It's like dynamic allocation, but the DHCP server keeps a table of past IP address assignments, so it can preferably assign a client the same IP address it had before..
