How to reconfigure 192.168.170.198 to localhost?

Question

Computer networks

Hey! This is the first time I've encountered such a problem, I don't even understand how it happened even.
All programs that worked on localhost are now available at: 192.168.170.198

This confuses me. It would be desirable to come, on habitual on localhost. I hope that you will help where to dig.

Answer 1

localhost -> 127.0.0.1
192.168 - the gray network is more external.
go to localhost, no one bothers.
available - because they listen to the address '*'
man "lsof", well, the so-called bind, listen parameters for services
