Let’s say you are running a poor man’s website where you are just testing stuff but have no real intention of buying a domain name or paying your ISP to give you a static IP address.

If you want to access your test site remotely, you need to know your public IP address, however your home ISP gives you a dynamic public IP address and every time you have a power failure, or reboot your router, you are assigned a brand new public IP address. This makes it very annoying if you are testing your site remotely.

Sure, you could use a Dynamic DNS service to keep track of when your public IP address changes, but what if you have a paranoid client who does not want to use even Dynamic DNS? How do you keep track of your new public IP without having to get to your internal network to read it each time?

What you need is a way to be able to have the system send you an email with your current public IP address so that there is no guess work involved. But how do we do this?
