Hi again Owen,
if you open your hosts.txt file just before the 127.0.0.1 IPS you can see:
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
127.0.0.1 is the loopback Internet protocol 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. The same convention is defined for computer’s that support IPv6 addressing using the connotation of ::1. Establishing a connection using the address 127.0.0.1 is the most common practice. The loopback construct gives a computer or device capable of networking the capability to validate or establish the IP stack on the machine.

Thanks for the quick reply!

When you say they are “legit”, what do you mean? Are they third-parties, or something else? Not really concerned, just interested.

Hi Fedele,
can you post them here as a comment or send us a screenshot of the file ?
