Yes, this is completely possible, but this is not a very good idea:

Most ISP's use dynamic IP's, so you cannot reliably identify somebody as
a repeat user based on their IP address.  They can come back with
another IP, and another person can come back with the first person's IP.

If you want to do this, you'll find cookies to be a lot more reliable to
you...but they can be deleted off the user's machine, of course...

Kind regards,

Maybe in order to understand mankind, we have to look at the
word itself: "Mankind".
Basically, it's made up of two separate words - "mank" and "ind".

What do these words mean?
It's a mystery, and that's why so is mankind.
