DHCP (Dynamic Host Configuration Protocol) is a network protocol that automatically assigns IP addresses to devices on a network. By using the "ipconfig/renew" command, the device sends a request to the DHCP server to renew its IP address lease, allowing it to obtain a new IP address if necessary.Rate this question:
