Instant Wireless® Series Appendix B: How to Ping Your ISP's E-mail & Web Addresses Virtually all Internet addresses are configured with words or characters (e.g., www.linksys.com, www.yahoo.com, etc.) In actuality, however, these Internet addresses are assigned to IP addresses, which are the true addresses on the Internet. For example, www.yahoo.com is 66.218.71.87 (this IP address may change). Type it into your web browser and you will wind up at the Linksys home page every time. There are servers that translate the URL to an IP address; this is called the Domain Name System (DNS). IP and web addresses, however, can sometimes be long and hard to remember. Because of this, certain ISPs will shorten their server addresses to single words or codes on their users' web browser or e-mail configurations. If your ISP's email and web server addresses are configured with single words (www, e-mail, home, pop3, etc.) rather than whole Internet addresses or IP addresses, the Router may have problems sending or receiving mail and accessing the Internet. This happens because the Router has not been configured by your ISP to accept their abbreviated server addresses. The solution is to determine the true web addresses behind your ISPs code words. You can determine the IP and web addresses of your ISP's servers by "pinging" them. Important: If you don't have your ISP's web and e-mail IP addresses, you must either get them from your ISP or follow these steps prior to connecting the Router to your network.

mail
). Press
the
Enter
key. Information such as the following data, taken from a ping of
Microsoft Network’s e-mail server, will be displayed.

Appendix B:How to Ping Your
ISP’s E-mail &Web Addresses
Virtually all Internet addresses are configured with words or characters (e.g.,
www.linksys.com
,
www.yahoo.com
, etc.) In actuality, however, these Internet
addresses are assigned to IP addresses, which are the true addresses on the
Internet. For example,
www.yahoo.com
is 66.218.71.87 (this IP address may
change). Type it into your web browser and you will wind up at the Linksys
home page every time. There are servers that translate the URL to an IP
address; this is called the Domain Name System (DNS).
IP and web addresses, however, can sometimes be long and hard to remember.
Because of this, certain ISPs will shorten their server addresses to single words
or codes on their users’web browser or e-mail configurations. If your ISP’s e-
mail and web server addresses are configured with single words (
www
,
e-mail
,
home
,
pop3
, etc.) rather than whole Internet addresses or IP addresses, the
Router may have problems sending or receiving mail and accessing the
Internet. This happens because the Router has not been configured by your ISP
to accept their abbreviated server addresses.
The solution is to determine the true web addresses behind your ISPs code
words. You can determine the IP and webaddresses of your ISP’s servers by
“pinging” them.
Important
:If you don’t have your ISP’s web and e-mail IP
addresses, you
must
either get them from your ISP or follow these
steps
prior
to connecting the Router to your network.
