in reply to Script to Notify of Public IP Change

Well, it looks as thoough there is no provision for the wget to fail; I suspect that when it does fail it doesn't return a valid IP address! :-)

The simple answer is that you could have it simply not perform any action if the ip returned from the wget is blank, or even does not match a regex.

    I figured I would have to do as much. I'm actually surprised I didn't add that in there when I was writing it. I guess I also wanted to have others look at the whole thing to see if it was okay or there was a simpler way to do what I am doing.
