-- Fix _is_localhost to not treat 0.0.0.0 from DNS as localhost.

-- On FreeBSD, socket.gethostbyname() returns "0.0.0.0" for NXDOMAIN instead of
|
|
-- raising socket.gaierror, causing non-existent domains to be misidentified as
|
|
-- localhost. The 0.0.0.0 case is already handled by the _LOCALHOST_NAMES check
|
|
-- above when it appears as a URL hostname, so the DNS resolution check for
|
|
-- 0.0.0.0 is unnecessary and harmful on FreeBSD.
