What is an IP address, and why do I need to know it?

There are many situations where you may need to know your Internet connection's IP address - remote technical support, gaining access to a corporate network, running your own web or email server just to name a few. Your internet service provider will often provide a dynamic IP address which changes periodically, but in some cases may provide a static IP address - ideal for running servers and for using DNS to point a domain to it. A static IP address doesn't change when you reconnect to the Internet.
