Configuring IPv6 DNS

IPv6 DNS can be configured only at the CLI.

IPv6 Domain Name System (DNS) is responsible for translating domain names into IPv6 addresses. Like

IPv4 DNS, IPv6 DNS includes static domain name resolution and dynamic domain name resolution. The

functions and implementations of the two types of domain name resolution are the same as those of IPv4

DNS. For more information, see "Configuring IPv4 DNS."

Configuring the IPv6 DNS client

This section explains how to configure static and dynamic domain resolution for the IPv6 DNS client.

Configuring static domain name resolution

Configuring static domain name resolution refers to specifying the mappings between host names and

IPv6 addresses. Static domain name resolution allows applications such as Telnet to contact hosts by

using host names instead of IPv6 addresses.

Follow these guidelines when you configure static domain name resolution:

• A host name can be mapped to one IPv6 address only. If you map a host name to different IPv6

addresses, the last configuration takes effect.

• You can configure up to 50 mappings between domain name and IPv6 address on a device.

To configure static domain name resolution:

Ste

Command

Remarks

1. Enter system view.

system-view N/A

2. Configure a mapping between a host

name and an IPv6 address.

ipv6 host hostname

ipv6-address

Not configured by default.

Configuring dynamic domain name resolution

To send DNS queries to a correct server for resolution, you must enable dynamic domain name resolution

and configure a DNS server.

In addition, you can configure a DNS suffix that the system automatically adds to the provided domain

name for resolution.

Follow these guidelines when you configure dynamic domain name resolution:

• You can configure up to six DNS servers, including those with IPv4 addresses on a device.

• You can specify up to ten DNS suffixes on a device.
