A question about Localhost with Safari

[Michael Crawford]

DNS is a protocol, not an API.  To the extent that hosts is used, it's
because developer of the software that implements the protocol chooses
to use it.

It's a PITA if it's not used - I quite commonly set up small networks
in my own office, with static IPs hardwired into my hosts files.
