Those are the direct paths and it's system global.

BTW. 0.0.0.0 is not "your own IP", that would be 127.0.0.1. 0.0.0.0 is non-routable, so always resulting in error.

Strange. Neither sportlight or alfred can find it. (and alfred does search though system files)

The file name is just “hosts” and it’s located in a folder called “etc” - maybe that helps? I think there is also a macOS setting that hides certain system files. You may have to unhide it first.
