application, for .local it's handled by mDNS, and for .localhost it's
special cased in the stub client library.
But it isn't. Go read the library code. There isn't magic for
localhost in there. The code looks in /etc/hosts before looking in
the DNS (normally) if there is a gethostbyname/getaddrinfo etc.
call. This allows the administrator to override the DNS for specific
names on this machine for those calls. This makes "telnet localhost"
work. It doesn't make lots of other stuff that should work succeed.
I'd say that's special case, since nearly every /etc/hosts I've looked at
only conains an entry for localhost, and perhaps a useless 255.255.255.255
for broadcasthost.
