My IP address is wrong! How can that be?
If your computer is located behind a firewall, the firewall may be
hiding your computer's actual IP address from myIPaddress.com. In
which case the IP address displayed is actually the IP address of the
firewall, not your computer.

Similarly, if your computer is behind a "proxy server" or "web cache"
(i.e., a computer that intercepts requests for web pages in order to
speed up frequently-requested pages), the IP address displayed is
probably the IP address of the proxy server or web cache -- not your
computer.

Note that your computer may be behind a proxy server or web cache
without your knowledge! A number of companies and Internet Service
Providers use "transparent web caches", which intercept requests for
web pages without any special configuration of your computer.

Non-Routable (Private) IP Addresses
We recommend non-routable IP for home networks. These IP addresses
have been set aside for use in home and office networks, when it isn't
necessary (or even desirable) to use a public IP address. They are
especially useful to the DSL user who has multiple computers connected
to a single proxy server, firewall or router (see our Network Overview
for details).
Reserved IP addresses for private networks
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
For more information, see RFC 1918 Address Allocation for Private
Internets: http://www.faqs.org/rfcs/rfc1918.html
