A lot of people seem to ask this question, so I wrote this real quick.
One benefit of this over most other external IP grabbers, is it should work on all sites without you having to change the code. Most other IP grabbers are hard-coded to work with specific HTML. If that site goes down or changes their HTML, then they won't work like they should.
This can extract all IPs found on a website or just the first one it finds. I put all the code into a module so all you have to do is add the module to your project and call the ExtractIPs(HTML) function.
I didn't use regular expressions for this because I didn't want to add an unnecessary dependency.
