With DHCP, this entire process is automated and managed centrally. The DHCP server maintains a pool of IP addresses and leases an address to any DHCP-enabled client when it starts up on the network. Because the IP addresses are dynamic (leased) rather than static (permanently assigned), ...

gateway address, Domain Name System (DNS) server address, or IP address to a DHCP client, as shown in the following figure, the DHCP client cannot obtain the correct IP address and required information. The authorized user then fails to access the network and user information security is ...
(Domain Name System) server configuration details for all users connecting using DHCP leases, meaning there’s less manual setup involved when somebody joins up with a new network than there would be if every user had their own statically assigned unique address from an administrator somewhere else...
