ip name-server
Overview This command adds IPv4 or IPv6 DNS server addresses. The DNS client on your
device sends DNS queries to IP addresses in this list when trying to resolve a host
name. Host names cannot be resolved until you have added at least one server to
this list. A maximum of three name servers can be added to this list.
If you are running VRF-lite, you can add IPv4 or IPv6 DNS server addresses for either
the global VRF instance or for a specific VRF instance. Host names cannot be
resolved from within a VRF instance until you have added at least one name-server
to that VRF instance.
The no variant of this command removes the specified DNS name-server address.
Syntax
ip name-server < ip-addr > [suffix-list <domain-list> ]
no ip name-server < ip-addr > [suffix-list]
Syntax (VRF-lite) ip name-server [vrf < name >] < ip-addr >
no ip name-server [vrf < name >] < ip-addr >
Mode Global Configuration
Usage To allow the device to operate as a DNS proxy, your device must have learned
about a DNS name-server to forward requests to. Name-servers can be learned
through the following means:
• Manual configuration, using the ip name-server command
• Learned from DHCP server with Option 6
• Learned over a PPP tunnel if the neighbor advertises the DNS server
This command is used to statically configure a DNS name-server for the device to
use.
For more information about PPP and DNS, see the PPP Feature Overview and
Configuration Guide .
