5.4 The DDNS (Dynamic DNS) Screen
Dynamic DNS allows you to map your current dynamic IP address with one or
many dynamic DNS services so that anyone can contact you. SIP IP phones can
access the SIP server on the X6004 using a domain name (for instance
myhost.dhs.org, where myhost is a name of your choice) that will never change
instead of using an IP address that changes each time you reconnect.
First of all, you need to have registered a dynamic DNS account with
www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP
server that would still like to have a domain name. The Dynamic DNS service
provider will give you a password or key.
5.4.1 DYNDNS Wildcard
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be
aliased to the same IP address as yourhost.dyndns.org. This feature is useful if
you want to be able to use, for example, www.yourhost.dyndns.org and still reach
your hostname.
If you have a private WAN IP address, then you cannot use Dynamic DNS.
