6. Using the Dynamic DNS (DDNS)
•
What is DDNS?
The DDNS service, an IP Registry provides a public central database where
information such as email addresses, hostnames, IPs etc. can be stored and
retrieved. This solves the problems if your DNS server uses an IP associated
with dynamic IPs.
Without DDNS, we always tell the users to use the WAN IP of the P-660H-Tx
v2 to access the internal server. It is inconvenient for the users if this IP is
dynamic. With DDNS supported by the P-660H-Tx v2, you apply a DNS name
(e.g., www.zyxel.com.tw) for your server (e.g., Web server) from a DDNS
server. The outside users can always access the web server using the
www.zyxel.com.tw regardless of the WAN IP of the P-660H-Tx v2.
