How do I Find the IP Address for Embarq 660 DSL Modem?

By Eoghan McCloskey

DSL modems differ from other modem types in that they must log in to your Internet service provider's (ISP's) DSL network, with a username and password assigned to your account by your ISP, before you will be able to browse the Internet. This username and password, along with other vital connection information, is saved on the internal modem interface, which is accessed by typing the modem's local access IP into an Internet browser. Knowing this IP address, therefore, is a vital part of setting up your Internet connection and ensuring its consistency.

Things You'll Need

  • Ethernet cable

Step 1

Bypass any network devices. In order for the computer to see the modem's local IP address, it is first necessary to bypass any home networking equipment like routers, switches and hubs that will show a different IP when connected to the modem. Locate the Ethernet port coming out of the back of your Embarq 660 DSL modem and trace it to whatever it is plugged into. If it plugs directly into your computer, there is nothing to bypass. If it plugs into any router or other home-networking device however, unplug the Ethernet cable from the device and plug it directly into one of the computer's Ethernet ports.

Step 2

"Powercycle" the modem. Devices that use Ethernet connections need to be reset before they will recognize a new connection. To perform this reset, simply unplug the power cord from the DSL modem for a full 30 seconds and plug it back in. Restart the computer and you are now ready to determine the modem's IP.

Step 3

Run an ipconfig command. Open the "Start" menu and click "All Programs." Click "Accessories" and then click on "Command Prompt." You should now see a black and white DOS screen with a blinking cursor. Type "ipconfig" and press enter. This command usually generates a lot of output; look for a line among the output that reads "IP address" or "IPv4 address." Open an Internet browser; type that address into the address bar and press enter. If you see the modem's configuration page, you have successfully found out the modem's login IP.

Step 4

Check the modem itself. If you were not able to find the local access IP using ipconfig, sometimes the local access IP is printed on a sticker on the underside of the modem. If not, check the documentation that came with your modem if you still have it.

Step 5

Contact your ISP as a last resort and ask them what your IP address is for the modem. If you purchased the modem on your own and not from an ISP, contact the manufacturer of the modem.
