BOOTP Client
After you specify an interface of a device as a BOOTP client, the interface
can use BOOTP to get information (such as IP address) from the BOOTP
server. This document describes:

DNS
Used in the TCP/IP application, Domain Name System (DNS) is a
distributed database which provides the translation between domain name
and the IP address. This document describes:
