No, we're checking the 'localhost' alias. And besides, if we use 255.0.0.0
as network mask then yes, we shoud/must not use 127.0.0.0, as this is the
network address, so it's a lot safer to use 127.0.0.1 in my opinion. I've
just remembered all those things about IP setups (I had some trouble with
settig up IPs in Linux one time :) )
