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.
