4.18  Dynamic DNS 
Choose menu “Dynamic DNS”, and you can configure the Dynamic DNS function.   
The Router offers the DDNS (Dynamic Domain Name System) feature, which allows the hosting 
of a website, FTP server, or e-mail server with a fixed domain name (named by yourself) and a 
dynamic IP address, and then your friends can connect to your server by entering your domain 
name no matter what your IP address is. Before using this feature, you need to sign up for DDNS 
service providers such as www.comexe.cn,  www.dyndns.org,  or  www.no-ip.com
. The Dynamic 
DNS client service provider will give you a password or key. 
4.18.1  Comexe.cn DDNS 
If  the  dynamic DNS Service Provider  you  select is www.comexe.cn, the page will appear as 
shown in Figure 4-104.
