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
2.
Write down the web address returned by the ping command
. (In the
example above: mail.msnv3.occa.home.com.) 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.
3.
At the DOS command prompt
, type "ping mail" (assuming that the
location 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.

Packets: Sent = 4, Received = 4, Lost = 0 (0%
loss),
Approximate round trip times in milli-seconds:

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, however, usually don’t. Because of this, you’re likely to have less
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 fol-
lowing data will be displayed.

• Straight-Through Cabling
•Cross-Over Cabling
Crimping Your Own Network Cables
Twisted-Pair Cabling
There are different grades, or categories, of twisted-pair cabling. Category 5
is the most reliable and is highly recommended. Category 3 is a good second
choice. Straight-through cables are used for connecting computers to a hub.
Crossover cables are used for connecting a hub to another hub (there is an
exception: some hubs have a built-in uplink port that is crossed internally,
which allows you to link or connect hubs together with a straight-through
cable instead).
You can buy pre-made Category 5
cabling, or cut and crimp your own.
Category 5 cables can be purchased or
crimped as either straight-through or
crossover. Inside a Category 5 cable
are 8 thin, color-coded wires inside
that run from one end of the cable to
the other. All 8 wires are used. In a
straight-through cable, wires 1, 2, 3,
and 6 at one end of the cable are also
wires 1, 2, 3, and 6 at the other end. In
a crossover cable, the order of the
wires change from one end to the
other: wire 1 becomes 3, and 2
becomes 6. See the diagrams on the
next page for more
detailed information on
straight-through and
crossover cabling.
To determine which wire is wire number 1, hold the cable
so that the end of the plastic RJ-45 tip (the part that goes
into a wall jack first) is facing away from you. Face the
clip down so that the copper side faces up (the springy clip
will now be parallel to the floor).When looking down on
the copper side, wire 1 will be on the far left.
