Bit of background
The internet is run on a system called TCP/IP.
Every computer connected to the internet has an IP address in the format 111.222.333.444.
Think of it a bit like a phone number, when you dial a phone number it knows where to route the call.
Well with an IP address if you want to connect to a computer it routes it to the correct IP address.
Many computers that connect to the interent are given a temporary IP address by their ISP (internet service provider).
So one day you may be 111.222.333.444, the next day 111.222.333.555.
A static IP address is where you specify an IP address and you stay with that address every time you connect to your ISP.
Unless you have changed it then I doubt whether you have a static IP address, most of us have a temporary IP address.
