DNS Resolver for IPv6

— Continued from the previous page. —

The no form of the command removes the specified address from the server address list configured on the switch.

<ip-addr>: Specifies the address of an IPv6 or IPv4 DNS server.

Syntax:. [no] ip dns domain-name < domain-name-suffix>

Used at the global config level to configure the domain suffix that is automatically appended to the host name entered with a command supporting DNS operation. Configuring the domain suffix is optional if you plan to use fully qualified domain names in all cases instead of just entering host names.

You can configure up to three addresses for DNS servers in the same or different domains. However, you can configure only one domain name suffix. This means that a fully qualified domain name must be used to resolve addresses for hosts that do not reside in the same domain as the one you configure with this command. That is, if the domain name suffix and the address of a DNS server for that same domain are both configured on the switch, then you need to enter only the host name of the desired target when executing a command that supports DNS operation. But if the DNS server used to resolve the host name for the desired target is in a different domain than the domain configured with this command, then you need to enter the fully qualified domain name for the target.

The no form of the command removes the configured domain name suffix.

For example, suppose you want to configure the following on the switch:

■the address 2001:db8::127:10 which identifies a DNS server in the domain named mygroup.procurve.net

■a priority of 1 for the above server

■the domain suffix mygroup.procurve.net

Assume that the above, configured DNS server supports an IPv6 device having a host name of “mars-1” (and an IPv6 address of fe80::215:60ff:fe7a:adc0) in the “mygroup.procurve.net” domain. In this case you can use the device's host name alone to ping the device because the mygroup.procurve.net domain has
