ipv6 name-server server-ipv6_address1 [server-ipv6_address2 [server-ipv6_address3]]
Syntax Definitions
server-ipv6_address1 The IPv6 address of the primary IPv6 DNS server to query for host
lookup. Specifying the primary IPv6 DNS address is mandatory.
server-ipv6_address2 The IPv6 address of the secondary IPv6 DNS server to query for host
lookup. This server will be queried only if the desired host name is not
able to be resolved by the primary IPv6 DNS server. A second IPv6
address is optional.
server-ipv6_address3 The IPv6 address of the IPv6 DNS server with the lower priority. This
server will be queried only if the desired host name is not able to be
resolved by both the primary and secondary IPv6 DNS servers. A third

Usage Guidelines
• Configuration of the DNS resolver to resolve any host query requires that you first set the default
domain name with the ip domain-name command and enable the DNS resolver function with the ip
domain-lookup command before you specify the IPv6 addresses of the IPv6 DNS servers by using the
ipv6 name-server command.
• You cannot use multicast, loopback, link-local and unspecified IPv6 addresses for specifying IPv6
DNS servers.
• You can configure up to three IPv6 DNS servers and three IPv4 DNS servers in a switch.
