Configuring the Domain Name and Domain Name Server

Configure a domain name and Domain Name Server (DNS) for your router to contact other devices on your network efficiently. Use the following guidelines:

•To define a default domain name that the Cisco IOS XR software uses to complete unqualified hostnames (names without a dotted-decimal domain name), use the domain-namecommand in global configuration mode.

•To specify the address of one or more name servers to use for name and address resolution, use the domain name-servercommand in global configuration mode. If no name server address is specified, the default name server is 255.255.255.255 so the DNS lookup can be broadcast to the local network segment. If a DNS server is in the local network, it replies. If not, there might be a server that knows how to forward the DNS request to the correct DNS server.

•Use the show hosts command in EXEC mode to display the default domain name, the style of name lookup service, a list of name server hosts, and the cached list of hostnames and addresses.
