Whenever you connect to the internet, you are giving a unique 4 number Internet Protocol Address (IP Address). Your IP address is how data from your computer to a website is how data finds its way back and forth. Your IP address may change each time you attach to your ISP. If your IP address stays the same from connection to connection, you are said to have a static IP address. If it changes each time you connect, you are said to have a Dynamic IP Address.
IP addresses can be important in the context of search engine submission because some search engines have been known to ignore submissions from any one IP over a certain limit.
