Configuring IPv6 DNS 
Configure a static host name to IPv6 address mapping 
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.

Configure 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.
