Configuring Dynamic DNS
If your network has a permanently assigned IP address, you can register a domain name and have
that name linked with your IP address by public Domain Name Servers (DNS). However, if your
Internet account uses a dynamically assigned IP address, you will not know in advance what your
IP address will be, and the address can change frequently. In this case, you can use a commercial
dynamic DNS service that will allow you to register your domain to their IP address, and will
forward traffic directed at your domain to your frequently-changing IP address.
The router contains a client that can connect to a dynamic DNS service provider. To use this
feature, you must select a service provider and obtain an account with them. After you have
configured your account information in the router, whenever your ISP-assigned IP address
changes, your router will automatically contact your dynamic DNS service provider, log in to your
account, and register your new IP address.
How to Configure Dynamic DNS
1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name
of admin, default password of password, or using whatever User Name, Password and LAN
address you have chosen for the router.
Warning: If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x,
the dynamic DNS service will not work because private addresses will not be
routed on the Internet.
