Knowing when your IP changes

Got a little question I was wondering about.

I have a dynamic IP with my ISP and everytime it changes I never know what the new one is unless I go to the computer manually and pull up ipconfig. Is there a program out there that monitors my IP and can send me the new IP when it changes to my email?

Google: ip change monitor

I should of known to google, but I was in a hurry to leave and was already here at AO so I thought I'd ask that question here.

Thanks

Here is a scribt that will let you no what your ip addess is, i got it from the microsoft web sight along with some other sample scripts just save it with the vbs extention and double click it to see what your ip address is.
