Configuration Guide 20. IPv6 Routing
20.6 DNSv6
DNS is a hierarchical naming system for computers, devices, or any resources connected
to a network. DNS is used to resolve hostnames into IP addresses, and to enforce naming
conventions for devices in the network and/or domain.
DNS configuration for devices can be either static – administrator configured – or acquired
dynamically through DHCP.
While working with DHCPv6 and DNSv6, the DNS server IPv6 address is not sent to the
clients if Neighbor Discovery or Router Advertisement is used. For this scenario, static IPv6
addresses need to be configured.
20.6.1 DNSv6 Configuration
The following describes DNSv6 configuration..
20.6.1.1 Global Configuration

(config-data)# ip dns server
<all|static>

or dynamic).
(config-data)# ip name-server
server1ipv6 [server2ip] all

case of static configuration.
