dynamic. With DDNS supported by the P-663HN-51, 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-663HN-51.
When the ISP assigns the P-663HN-51 a new IP, the P-663HN-51 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., www.zyxel.com.tw) is still usable.
The DDNS servers the P-663HN-51 supports currently are
WWW.DYNDNS.ORG and
and update the WAN IP to.

DDNS server.
