Only the first element of the array is an IP Address, correct?
Makes is a little more difficult to do validation on it..
They are both IP addresses - in reverse byte order, suitable for
a DNS PTR lookup:
71.53.92.40 -> 40.92.53.71 (Microsoft)
5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.4.0.0.0.2.8.0.6.9.0.1.3.0.6.2
-> 2603:1096:0820:0040::5 (Microsoft)
SA::Util.pm:
# Given a quad-dotted IPv4 address or an IPv6 address, reverses the
order
# of its bytes (IPv4) or nibbles (IPv6), joins them with dots, producing
# a string suitable for reverse DNS lookups. Returns undef in case of a
# syntactically invalid IP address.
