On Linux you must set a flag to tell it not to consider the possibility
that what you are passing it is not a numeric address:
node specifies either a numerical network address (for IPv4,
numbers-and-dots notation as supported by inet_aton(3); for IPv6,
hexadecimal string format as supported by inet_pton(3)), or a
network hostname, whose network addresses are looked up and
resolved. If hints.ai_flags contains the AI_NUMERICHOST flag
then node must be a numerical network address. The
AI_NUMERICHOST flag suppresses any potentially lengthy network
host address lookups.
CONFORMING TO
POSIX.1-2001. The getaddrinfo() function is documented in RFC 2553.
