11.2 Using DDNS

Some ISP's do change your WAN IP-Address once a month or even every week. In
that case, you are not longer able to access the surveillance recorder externally. In
such a case, the use of DDNS is the ideal solution: Thanks to DDNS you can access
the surveillance recorder externally, no matter if your WAN IP address has been
changed.

11.2.1 What is DDNS?

With the use of DDNS you can link a domain name to your WAN IP-Address
permanently, even if your WAN IP-Address has been changed. Without DDNS, you
would lose the connectivity with your network equipment the moment your WAN IP-
Address has been changed.
A big advantage of using DDNS is the use of a fixed name, instead of the use of an
IP-Address. You only have to remember the self-created domain name instead of a
whole number sequence. Also, your network equipment will remain accessible, even if
your WAN IP-Address has been changed. The domain name, linked to the WAN IP-
Address, will remain the same. This way, you will always be able to login if you have
an Internet connection available.
Hint: Create a DDNS account on: www.dyndns.org (Paid service) or create a DDNS
account on http://www.no-ip.com (Free service). There are many other DDNS services
which can be found using the internet.
