Static DNS
You can specify DNS mapping between names and IP addresses for your local hosts. In the
Advanced section of the main menu, select Static DNS. The following screen displays:
To map additional local host names to IP addresses, click the More Mapping hyperlink.
When you have finished specifying the static DNS configuration, click Apply so that your changes
take effect.
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 to register your domain to their IP address, and forward traffic directed at
your domain to your frequently changing IP address.
The modem 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 modem router, whenever your ISP-assigned IP address
changes, your modem router will automatically contact your Dynamic DNS service provider, log
in to your account, and register your new IP address.
