ipv6 dns server ipv6-address [ interface-type interface-number ]

By default, no DNS server address is specified.

Configuring the DNS proxy

Restrictions and guidelines

You can specify multiple DNS servers. The DNS proxy forwards a request to the DNS server that has

the highest priority. If having not received a reply, it forwards the request to a DNS server that has the

second highest priority, and so on.

You can specify both an IPv4 address and an IPv6 address.

• A DNS proxy forwards an IPv4 name query first to IPv4 DNS servers. If no reply is received, it

forwards the request to IPv6 DNS servers.

• A DNS proxy forwards an IPv6 name query first to IPv6 DNS servers. If no reply is received, it

forwards the request to IPv4 DNS servers.

Procedure

1. Enter system view.

system-view

Configuring DNS spoofing

Restrictions and guidelines

• You can configure only one replied IPv4 address and one replied IPv6 address. If you execute

the command multiple times, the most recent configuration takes effect.

• After DNS spoofing takes effect, the device spoofs a DNS request even though a matching

static DNS entry exists.

Prerequisites

The DNS proxy is enabled on the device.

No DNS server or route to any DNS server is specified on the device.
