Step One: Pinging an IP Address

The first step to determining your ISP’s web and e-mail server address is to ping its IP address.

1.Power on the computer and the cable or DSL modem, and restore the network configuration set by your ISP if you have since changed it.

2.Click Start, then Run, and type command. This will bring up the DOS window.

3.At the DOS command prompt, type ping mail (assuming that the loca- tion for which you’re trying to find an IP address is configured as mail). Press Enter. Information such as the following data, taken from a ping of Microsoft Network’s e-mail server, will be displayed.

Ping statistics for 24.53.32.4:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms

4.Write down the IP address returned by the ping command. (In the example above: 24.53.32.4.) This IP address is the actual IP address of the server mail, or any other word or value you have pinged.

Step Two: Pinging for a Web Address

While the IP address returned above would work as your e-mail server address, it may not be permanent. IP addresses change all the time. Web addresses, how- ever, usually don’t. Because of this, you’re likely to have fewer problems by configuring your system with web addresses rather than IP addresses. Follow the instructions below to find the web address assigned to the IP address you just pinged.

1.At the DOS command prompt, type ping -a 24.53.32.4, where 24.53.32.4 is the IP address you just pinged. Information such as the following data will be displayed.

C:\>ping -a 24.53.32.4

Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms

2.Write down the web address returned by the ping command (In the example in Figure C-2:mail.msnv3.occa.home.com is the web address). This web address is the web address assigned to the IP address you just pinged. While the IP address of mail could conceivably change, it is likely that this web address will not.

3.Replace your ISP’s abbreviated server address with this extended web address in the corresponding Internet application (web browser, e-mail application, etc.).

Once you have replaced the brief server address with the true server address, the Router should have no problem accessing the Internet through that Internet application.
