I don't know how we could test that, it's only in the logs

Indentation on this code is bad. Maybe try to run go fmt?

Also, this might just deserve a new function call instead of adding it here?

A function that might include the whole address parsing (from req.RemoteAddr and caddy client_ip variable) ?
