There is no place like 127.0.0.1
We've done DEVshirt's version of a classic tee: "There is no place like 127.0.0.1" .
Translation for non-techies: "there is no place like home".
Since most of us programmers are technologists, we've illustrated it with a futuristic home.
We hope that you'll enjoy our futuristic version of localhost 😛
127.0.0.1 Networking deep dive
All messages generated by TCP/IP application software contain IP addresses for their intended recipients. TCP/IP recognizes 127.0.0.1 as a special IP address. The protocol checks each message before sending it to the physical network. Then, it automatically re-routes any messages with a destination of 127.0.0.1 back to the receiving end of the TCP/IP stack.
Did you know:
To improve network security, TCP/IP also checks incoming messages arriving on routers or other network gateways and discards any that contain loopback IP addresses. This doublecheck prevents a network attacker from disguising their traffic as coming from a loopback address.
