[Sysname] ip host aaa 10.110.0.1

specified, the undo ipv6 dns server command removes all DNS server IPv6 addresses on the public
network or the specified VPN.

Parameters
ipv6-address: Specifies the IPv6 address of a DNS server.
interface-type interface-number: Specifies the output interface by its type and number. If no interface is
specified, the device forwards DNS packets out of the output interface of the matching route. You must
specify the output interface when the IPv6 address of the DNS server is a link-local address.
vpn-instance vpn-instance-name: Specifies the name of an MPLS L3VPN, a case -sensitive string of 1 to 31
characters. To specify a DNS server IPv6 address on the public network, do not use this option.
Usage guidelines
For dynamic DNS, the device sends DNS query request to the IPv6 DNS servers in the order their IPv6
addresses are specified.
You can specify DNS server IPv6 addresses for the public network and up to 1024 VPNs, and specify a
maximum of six DNS server IPv6 addresses for the public network or each VPN.
