IPv6 DNS Configuration Examples
Static Domain Name Resolution Configuration Example
Network requirements
As shown in Figure 2-1 , static domain name resolution is configured on the Switch and thus the Switch
can use the domain name host.com to access the host whose IPv6 address is 1::2.
Figure 2-1 Network diagram for static domain name resolution
Configuration procedure
# Configure a mapping between host name host.com and IPv6 address 1::2.
<Switch> system-view
[Switch] ipv6 host host.com 1::2
# Enable IPv6 packet forwarding.
[Switch] ipv6
# Use the ping ipv6 host.com command to verify that the Switch can use static domain name
resolution to resolve domain name host.com into IPv6 address 1::2.
[Switch] ping ipv6 host.com
PING host.com (1::2):

Dynamic Domain Name Resolution Configuration Example
Network requirements
As shown in Figure 2-2 , the IPv6 address of the DNS server is 2::2/64 and the name suffix is com. The
mapping between domain name host and IPv6 address 1::1/64 is stored in the com domain.
