DNS makes a number of restrictions on hostnames, and we apply them too,
though we are even more strict about it than DNS is.

Setting 127.0.0.1 as hostname is very confusing since it is actually an
IP address and many programs try parsing host specifications as ip
adddresses before they try to resolve them.
