Strange data in log: connection from localhost.

Hello,
does anyone have any idea what's going on?
I’ve found in log a lot of strange record (more than 400 in few days):
One, just for an example:

Looks like some random connection from the internet. That happens when your server is public.

Thank you very much Anton.
….so it’s nothing "dangerous"?
