HTTP/1.1 specifies exactly what to send in that case, namely the uri-host,
which would simply tbe the IP address in this case - URLs with ip literals are
perfectly fine and work with HTTP/1.1.

It might still be cause of a problem on the server side, but browser
behaviour is pretty much inversally the same for this case.
