Configuring DNS
The extent to which you enable DNS functions on the ProCurve Secure Router
depends on whether you want the router to simply be able to run the DNS
client or to act as a name server for your organization.
If you only want the router to act as a DNS client, you must:
enable DNS (which is enabled by default)
specify at least one external DNS server
You can also:
add entries for local hosts to the router's host table
If you want the router to act as a name server for hosts in your network, you
must:
enable DNS (which is enabled by default)
specify at least one external DNS server
add entries for local hosts to the router's host table
enable DNS proxy

Enabling DNS

The ProCurve Secure Router automatically supports DNS. You can turn DNS
on and off with the following global configuration mode command:
Syntax: [no] ip domain-lookup
This command enables the DNS client on the router. You can input Web
addresses instead of IP addresses for applications such as ping, Telnet, and
traceroute, and the router will either translate the names itself using its host
table or query its primary DNS server.
In order for the router to translate hostnames for itself, you must add entries
for hosts in its domain to its host table.
In order for the router to resolve the names of hosts outside its domain, you
must specify the IP address of the DNS server it should query.
The router will only act as a name server for connected hosts if you enable
DNS proxy. (See "Enabling the Router to Act as a Name Server" on page 12-10.)
