Hi, I am Kiru 👋 an indie hacker, a problem solver and vim-lover. I build projects to make the life of others and mine easier.

This page is intended to collect all my projects and some thoughts.

What is the difference between 127.0.0.1 and 0.0.0.0?

TIL 07.03.2017

  • binding 127.0.0.1 means listen to loopback interface
  • Process bound to 127.0.0.1 can only be accessed by other programs from the same machine

  • binding to 0.0.0.0 means listen to all interfaces ( e.g. all network interfaces connected to the machine )

  • on Mac 27.0.0.1 /32 is bound to loopback

  • on Windows 127.0.0.0 /8 is bound to loopback
