3-2-4-9 DDNS
The DDNS service (Dynamic Domain Name Service), an IP Registry provides a public central database
where information such as email addresses, host names, IP addresses etc. can be stored and retrieved.
This solves the problems if your DNS server uses an IP associated with dynamic IP addresses. When
the ISP assigns the Wireless Subscriber Gateway a new IP, the Wireless Subscriber Gateway must
inform the DDNS server the change of this IP so that the server can update its IP-to-DNS entry. Once
the IP-to-DNS table in the DDNS server is updated, the DNS name for your web server (i.e.,
xyz.dyndns.org) is still usable.
