Dynamic DNS
This chapter discusses how to configure your ZyXEL Device to use Dynamic DNS.
7.1  Dynamic DNS Overview  
Dynamic DNS allows you to update your current dynamic IP address with one or many 
dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You 
can also access your FTP server or Web site on your own computer 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. Your friends or relatives 
will always be able to call you even if they don't know your IP address.
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. 
7.1.1  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.
Note: If you have a private WAN IP address, then you cannot use Dynamic DNS.
See 
 for configuration instruction. 
7.2  Configuring Dynamic DNS 
To change your ZyXEL Device’s DDNS, click Dynamic DNS. The screen appears as shown.
See 
 for more information.
