6 Appendix C: How to Ping your ISP’s E-mail
and Web addresses
Virtually all Internet addresses are configured with words or characters
(e.g., www.corinex.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.corinex.com is actually
81.0.193.56 at the time of producing this User Guide. Type it into your web

There are servers that translate the URL to an IP address; these are called
Domain Name System (DNS) Servers. 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 your Corinex Powerline Router to your network.

the network configuration set by your ISP if you have changed it.
2. Click Start, then Run, and type command. This will bring up the
