    Because under RFC 1918,

    http://www.faqs.org/rfcs/rfc1918.html

    the document governing the use of private networks using TCP/IP, three ranges of IP addresses can be used for private networks:

    10.0.0.0 - 10.255.255.255 (10/8 prefix)

    172.16.0.0 - 172.31.255.255 (172.16/12 prefix)

    192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

    those are the only ranges of IP addresses that can be used in this fashion under IPv4. If and when IPv6 (a new method of addressing that provides much more flexibility) becomes so widely adopted that it's in use by consumers, there should be a new rule governing private networks at that time.

    192.168.0.0 through 192.168.255.255 are private IP addresses.

    These are "non routable" over the Internet. If you were to just pick some random Class C, if you don't use specific reserved private IP blocks, you WILL be using some public IP of some real site somewhere...Imagine if this practice were widespread.

    What if you happend to pick the IP block google.com actually uses? Yahoo? Ebay? For that reason, specific blocks in the class A, B and C range were setup to never be used over public routable networks. This makes them safe for you to use on your private LAN without worry that you are inadvertantly using someones real, routable, public IPs.
