There are so many things wrong with that code, it's really quite amazing it works at all!
Lets ignore the fact that I have no idea what this 'clip' command actually is, and just 'assume' it's some magic program that takes STDOUT from a command-line application and inserts it into the clipboard..
You're doing a hard-loop checking the content of a variable of which doesn't exist, which basically sucks *ALL* CPU cycles away from everything else. So whilst looping hard, you may get lucky and have the 'odd' cycle of which the previous 'run' can actually do something in. Yay.
You'd be better off breaking the alias int two parts, one to do the ipconfig call, the other, after a /timer, reads from the clipboard. You could even make it a self-calling timer so it could wait longer if necessary.
