Configuration procedure
# Configure a mapping between host name host.com and IPv6 address 1::2.

[Device] ipv6 host host.com 1::2
# Enable IPv6 packet forwarding.
[Device] ipv6
# 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.
[Device] ping ipv6 host.com

Dynamic domain name resolution configuration example
Network requirements
As shown in Figure 60 , the device wants to access the host by using an easy-to-remember domain name
rather than an IPv6 address. The IPv6 address of the DNS server is 2::2/64 and the server has a com
domain, which stores the mapping between domain name host and IPv6 address 1::1/64.
Configure dynamic domain name resolution and the domain name suffix com on the device that serves
as a DNS client so that the device can use domain name host to access the host with the domain name
host.com and the IPv6 address 1::1/64.
