FWIW, it seems IO::Socket::IP passes AI_ADDRCONFIG to getaddrinfo, which
then doesn't return ipv4 addresses because the host doesn't have
non-local ones, even though the address we're trying to resolve is
"127.0.0.1".

Passing either GetAddrInfoFlags => AI_NUMERICHOST or GetAddrInfoFlags =>
0 to both IO::Socket::IP->new calls in the test file lets it pass, by
turning off the smarts in getaddrinfo.

Cheers,
