Question
I see a lot of hits from 127.0.0.1. Should I block the IP?
Answer
127.0.0.1 is the loopback Internet protocol (IP) address also referred to as the “localhost.” The address is used to establish an IP connection to the same machine or computer being used by the end-user.
You would not want to block 127.0.0.1 as it is an essential part of your server's configuration.
