If you are working on an public internet or has a dynamic IP address on your broadand internet, there are may ways to find the current IP when in need. Now, you need not to go to the dedicated web service or launching tools to find the IP, because Google now answers your questions and shows your IP using the new seary query parameter [my ip], [my ip address], [show my ip], [what is my ip] and other similar queries.
To find your current IP address alloted to you by your ISP, just Google [my ip] or any other search query paramenter (metioned above) — the top result is your IP address.
“Just like a street address determines the recipient of a letter, an IP address (short for Internet Protocol address) is used to identify computers on the Internet. When your computer sends a request, such as a Google query, it tags the request with its IP address in order for the response to be sent back to your computer — just like a return address on a letter.[…]
When you type the query [ what is my ip ], Google will respond by showing you the IP address of the computer from which the query was received. In the simplest case, this IP address uniquely identifies your computer among all computers on the Internet,” explains Google.
