There's no place like 127.0.0.1

There's no place like 127.0.0.1 is a t-shirt slogan which is a play on the common American English saying, There’s no place like home, popularized by the 1939 movie The Wizard of Oz.

In computer networking the Localhost reserved IP address is guaranteed to be in every networked computer. In IPv4, we use 127.0.0.1; in IPv6 we use ::1. This is why the phrase sometimes appears as There’s no place like ::1

Since that address is on every machine, it is just like “home.” Always there, always safe, and local to you. It’s an inside joke for networking nerds.

Since that IP address is the same on every computer, you can double your nerd points by quoting Buckaroo Banzai and say, No matter where you go, there you are.
