Thank you both for your help i would love to solve this through creating a program, but some times you shouldn't re-invent the wheel going to take a look at this no-ip thing

Thanks again!

Solution #1: To answer your

Solution #1:

To answer your specific question, you would need a script on your server that would log the IP address of the client accessing it. For example, something like this on your server:

<?php
file_put_contents('ip.txt', $_SERVER['REMOTE_ADDR']);
?>

Then, whenever you want to know your IP address of your home network, just call up example.com/ip.txt (assuming that the PHP script is stored at example.com).

Now a computer from your home network will have to periodically load that PHP script from your server so it would update. The easiest way I can think of would be to write a small Windows program that sends a hit to that URL every few minutes. You could also add a meta refresh tag to that php script above that would tall a browser to refresh the page after a set amount of time, but then you would have to leave a browser open on a computer.

Solution #2:

There is a free Dynamic DNS service by No-IP and a couple other companies that will do all of this for you.

I vote for #2.

Edit: darn it, Matt beat me to it

Actually, I think you could even just use your no-ip subdomain when you connect to your VPN service (you wouldn't even have to check your account). Relentless.no-ip.org (for example) would always point you at the right place for your VPN.

You're on a Windows machine

You're on a Windows machine right? I think the easier solution would be signing up for No-IPs free DNS service, and using their Dynamic Update Client. It is usually used for web servers, but it doesn't really matter. All that matters is that when you login to your no-ip account, you'll see your up to date IP. It's not as cool as writing a program to do it, but it gets the job done.
