Configuring IPv6 DNS
Configuring a static IPv6 DNS entry
You can directly use a host name when applying telnet applications and the system will resolve the host
name into an IPv6 address. Each host name can correspond to only one IPv6 address. A newly
configured IPv6 address will overwrite the previous one.
Follow these steps to configure a static IPv6 DNS entry:
To do… Use the command… Remarks
Enter system view system-view —
Configure a static IPv6 DNS
entry ipv6 host hostname
ipv6-address
Required
Configuring dynamic DNS resolution
If you want to use the dynamic domain name function, you can use the following command to enable
the dynamic domain name resolution function. In addition, you should configure a DNS server so that a
query request message can be sent to the correct server for resolution. The system can support at most
six DNS servers.
