Dynamic Host Configuration Protocol (DHCP) enables users to dynamically and transparently assign reusable IP addresses to clients. Cisco IOS Easy IP Phase 2 includes the Cisco IOS DHCP Server, a RFC 2131-compliant DHCP server implementation on selected routing platforms.


Domain Name System (DNS) is the system in the Internet that maps names of objects (usually host names) into IP numbers or other resource record values. The namespace of the Internet is divided into domains, and the responsibility for managing names within each domain is delegated, typically to systems within each domain.
