3-2-16 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 WSG-401 a new IP, the WSG-401 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.
