Hi Chojin,

Sounds like you want to read Everything You Ever Wanted to Know About IP
Addresses:

http://www.3com.com/solutions/en_US/ncs/501302.html

It's no longer in html but you can download the 3 pdf files and read them
with acroread. Definitely a classic and well worth reading every now and
then.

HTH,

Dru
