3-2-5-8 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
UAG50 a new IP, the UAG50 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.
