Configuring Dynamic DNSIf 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 automatically contacts your Dynamic DNS service provider, logs in to your
account, and registers your new IP address.
How to Configure Dynamic DNS1. Log in to the modem router at its default LAN address of http://192.168.0.1 with its default
user name of admin and default password of password, or using whatever user name,
password, and LAN address you have chosen for the modem router.
2. In the main menu, under Advanced, select Dynamic DNS to display the following screen.
3. Access the website of one of the Dynamic DNS service providers whose names appear in the
Service Provider drop-down list, and register for an account. For example, for dyndns.org, go
to www.dyndns.org.
4. Select the Use a dynamic DNS Service check box.
