It might be helpful to point out the difference between an ISP and an IP address:
ISP = Internet Service provider. You can have numerous ISPs from the one computer. AOL, Comcast, Earthlink, etc. These are the companies who get you hooked up to the internet.
IP address = An identifying number for an internet computer. Each computer hooked up to the internet has a unique number. Kinda like a fingerprint that tells what computer is logged in (it doesn't matter which ISP you use).
So what happens is that Miss A sends a message from her computer using her AOL account. Miss B sends a message from her computer using her Comcast account. Miss C sends a message from her computer using her Earthlink account.
While it appears to the world that Miss A, B and C are all different people (and they very well could be), the important thing is EACH MESSAGE HAS COME FROM THE SAME COMPUTER They share an IP address!
Naturally, if Miss A were to send a message from her AOL account on another computer, this would show a different IP address.
Breaking it down even further, Rhiannon, Barbie, Alaska Fox and Lisa Williams may very well be different people, but they're using the same computer.
You can fool a lot of the people a lot of the time, but never underestimate the power of the geeks who have the ability to dig through the dirt to reveal the crap. Thanks Chev!
