IPv6 addresses are specified.
You can specify the following:
•
DNS server IPv6 addresses for the public network and up to 1024 VPNs.
•
A maximum of six DNS server IPv6 addresses for the public network or each VPN.

# Specify the DNS server IPv6 address as 2002::1 for the public network.
<Sysname> system-view
[Sysname] ipv6 dns server 2002::1

Parameters
ipv6-address: Specifies the IPv6 address used to spoof name query requests.
vpn-instance vpn-instance-name: Specifies the name of an MPLS L3VPN instance, a
case-sensitive string of 1 to 31 characters. To enable DNS spoofing on the public network, do not use
this option.
Usage guidelines
Use the ipv6 dns spoofing command together with the dns proxy enable command.
DNS spoofing enables the DNS proxy on the device to send a spoofed reply with an IPv6 address in
response to a type AAAA DNS request. Without DNS spoofing, the device does not forward or
answer a request if no DNS server is specified or no DNS server is reachable.
You can configure DNS spoofing for the public network and a maximum of 1024 VPNs. You can
specify only one replied IPv6 address for the public network or each VPN.
If you use the command multiple times, the most recent configuration takes effect.
Examples
# Enable DNS spoofing on the public network and specify 2001::1 as the translated IPv6 address.
