DNS Resolver
As mentioned under “Basic Operation” on page C-71, if the DNS entry config-
ured in the switch does not include the domain suffix for the desired target,
then you must use the target host’s fully qualified domain name with DNS-
compatible commands. For example, using the document server in Figure C-
29 as a target:
ProCurve# ping docservr.pubs.outdoors.com
10.28.229.219 is alive, time = 1 ms
ProCurve# traceroute docservr.pubs.outdoors.com
traceroute to 10.28.229.219
1 hop min, 30 hops max, 5 sec. timeout, 3 probes
1 10.28.192.2 1 ms 0 ms 0 ms
2 10.28.229.219 0 ms 0 ms 0 ms

Viewing the Current DNS Configuration
The show ip command displays the current domain suffix and the IP address
of the highest priority DNS server configured on the switch, along with other
IP configuration information. If the switch configuration currently includes a
non-default (non-null) DNS entry, it will also appear in the show run command
output.
ProCurve# show ip
