# Configure a mapping between host name host.com and IPv6 address 1::2.
<Device> system-view
[Device] ipv6 host host.com 1::2
# Use the ping ipv6 host.com command to verify that the device can use static domain name
resolution to resolve domain name host.com into IPv6 address 1::2.
[Sysname] ping ipv6 host.com

Dynamic domain name resolution configuration example
Network requirements
As shown in Figure 49, the DNS server at 2::2/64 has a com domain. The server stores the mapping
between domain name host and IPv6 address 1::1/64.
Configure dynamic DNS and the DNS suffix com on the device that acts as a DNS client. The device
can then use domain name host to access the host with the domain name host.com and the IPv6
address 1::1/64.
Figure 49 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 49.
