getnameinfo on macOS formats certain IPv6 addresses as IPv4-translated
addresses. The following pattern has been observed:
::ffff is formated as ::0.0.255.255
::fffe is formated as ::0.0.255.254
::ffff:0 is formated as ::255.255.0.0
::fffe:0 is formated as ::255.254.0.0
::ffff:0:0 is formated as ::ffff:0.0.0.0
::fffe:0:0 is formated as ::fffe:0:0
::ffff:0:0:0 is formated as ::ffff:0:0:0
The getnameinfo behavior causes a failure for:
DO_TEST_PARSE_AND_FORMAT("::ffff", AF_UNSPEC, true);
Use non-ambigious IPv6 for parse/format testing.
