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.

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.
You can configure a domain name suffix so that you only need to enter some fields of a domain name
and the system automatically adds the preset suffix for address resolution. The system can support at
most 10 domain name suffixes.
Follow these steps to configure dynamic DNS resolution:
Use the command...
system-view
ipv6 icmp-error { bucket
bucket-size | ratelimit
interval }*
Use the command...
system-view
ipv6 nd hop-limit value
Use the command...
