Dynamic domain name resolution configuration example
Network requirements
As shown in Figure 41, configure the DNS server to store the mapping between the host's domain name host and IPv6 address 1::1/64 in the com domain. Configure dynamic IPv6 DNS and the DNS suffix com on the device so that the device can use the domain name host to access the host.
Figure 41: Network diagram
Configuration procedure
Before performing the following configuration, make sure that:
The device and the host can reach each other.
The IPv6 addresses of the interfaces are configured as shown in Figure 41.
Configure the DNS server:
The configuration might vary by DNS server. The following configuration is performed on a PC running Windows Server 2008 R2. Make sure that the DNS server supports IPv6 DNS so that the server can process IPv6 DNS packets and its interfaces can forward IPv6 packets.
Select Start > Programs > Administrative Tools > DNS.
The DNS server configuration page appears, as shown in Figure 42.
Right-click Forward Lookup Zones, select New Zone, and then follow the wizard to create a new zone named com.
Figure 42: Creating a zone
Click Add Host.
The mapping between the IPv6 address and host name is created.
Figure 44: Adding a mapping between domain name and IPv6 address
On the DNS server configuration page, right-click zone com and select New Host.
Figure 43: Adding a host
Click Add Host.
The mapping between the IPv6 address and host name is created.
Figure 44: Adding a mapping between domain name and IPv6 address
On the page that appears, enter the host name host and the IPv6 address 1::1.
Click Add Host.
The mapping between the IPv6 address and host name is created.

Configure the DNS client:
# Specify the DNS server 2::2.
<Device> system-view [Device] ipv6 dns server 2::2
# Configure com as the DNS suffix.
[Device] dns domain com
Verifying the configuration
# Verify that the device can use the dynamic domain name resolution to resolve the domain name host.com into the IP address 1::1.
