DNS Resolver
Configuring switch "A" with the domain name and the IP address of a DNS
server for the domain enables the switch to use host names assigned to IP
addresses in the domain to perform ping and traceroute actions on the devices
in the domain. To summarize:
Entity:
DNS Server IP Address
Domain Name (and Domain Suffix for Hosts in
the Domain)
Host Name Assigned to
DNS Server
Fully Qualified Domain Name for the IP address

Switch IP Address
Document Server IP Address
With the above already configured, the following commands enable a DNS-
compatible command with the host name docserver to reach the document
server at 10.28.229.219.
ProCurve(config)# ip dns server-address 10.28.229.10
ProCurve(config)# ip dns domain-name pubs.outdoors.com
