8.6.6 Dynamic DNS

Dynamic domain name resolution (DDNS) is mainly used to achieve resolution
between fixed domain names and dynamic IP addresses. For a user that uses a
dynamic IP address, after the user obtains a new IP address in the Internet access,
the dynamic domain name software installed in the host sends the IP address to
the DDNS server provided by the DDNS service provider and updates the domain
name resolution database. When another user on the Internet tries accessing the
domain name, the dynamic domain name resolution server returns the correct IP
address.
Choose Network Application > Dynamic DNS and the Dynamic DNS page is
