Hashing functions would mainly be md5() and sha1().  As these are long, you may wish to truncate the hashes a bit.  Be sure to add in a "salt" or static unquifier unknown to the user, otherwise these hashes will also be reversable.

Some sites just hide the last two octets of the IP address.  That may also be a solution which may work a bit better with dynamic IPs, at the cost of being less unique.

Ok Thanks,

I'm going to do some more research on this issue. I know that what I want, has been done already, I just don't know How.

Here's my example: Godlike Productions

The reason I like it so much is that is short and sweet, no 34 characters, weird characters, just straight sequential numbers.

Every user id is based upon a unique ip address so no 2 are alike, including registered members. It's a custom system obviously, I just love to duplicated.
