SmartWare Software Configuration Guide	28 • DNS configuration

You can test the DNS server conﬁguration using the dns-lookupcommand as follows:

Example: Testing DNS server conﬁguration

node(cfg)#dns-lookup www.patton.com

Name: www.patton.com

Address: 209.49.110.5

Note The DNS resolver automatically learns domain name servers if it receives them through PPP or DHCP protocols. You can verify that the DNS resolver has received domain name servers by using the show dns-clientcommand as follows:

node(cfg)#show dns-client

The following DNS servers are currently available: Configured IP: 195.186.1.110

Discovered IP: 81.221.250.10 (Not used)

Discovered IP: 81.221.252.10 (Not used) node(cfg)#

Conﬁgured IP indicates a domain name server that has been conﬁgured as shown at the beginning of this section. Discovered IP indicates a domain name server that was learned automatically.

Enabling the DNS relay

DNS (Domain Name System) is a distributed database used in IP networks to provide the numerical IP address for a URL’s host name. There are DNS Servers, DNS Relays, and DNS Clients (see ﬁgure 45). DNS clients send queries with the host-name of interest to the DNS Server. The DNS server responds with the IP
