IPv6 DNS Configuration

Introduction to IPv6 DNS

IPv6 DNS is responsible for translating domain names into IPv6 addresses. Similar to IPv4 DNS, IPv6
DNS involves 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.

Configuring 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 steps to configure static domain name resolution:
Enter system view
Configure a mapping between a host
name and an IPv6 address
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.

Configuring Dynamic Domain Name Resolution

To send DNS queries to a correct server for resolution, dynamic domain name resolution needs to be
enabled and a DNS server needs to be configured.
In addition, you can configure a DNS suffix that the system will automatically add to the provided
domain name for resolution.
Follow these steps to configure dynamic domain name resolution:
To do...
Enter system view
To do...
Use the command...
system-view
Use the command...
system-view
ipv6 host hostname ipv6-address
