From TPU Reference

varcnaelda ricacc bocpasbolil Dynamic Host Configuration Protocol is a protocol that allows a server to assign network settings to a client. Most commonly DHCP is used to assign an IP, Gateway and DNS addresses and subnet mask to clients.

DHCP servers are very common, even though not everyone is aware of them every router comes with a simple DHCP server to give client computers an IP. Thanks to these servers you don't have to configure your internet settings with many connection types.
