Splits an IPv6 address into the IPv6 and IPv4 representation parts
RFC 4291 allows you to represent the last two parts of an IPv6 address using the standard IPv4 representation
Example: 0:0:0:0:0:0:13.1.68.3 0:0:0:0:0:FFFF:129.144.52.38
(string) (Required) An IPv6 address
(string[]) [0] contains the IPv6 represented part, and [1] the IPv4 represented part
File: wp-includes/Requests/IPv6.php
protected static function split_v6_v4($ip) {
if (strpos($ip, '.') !== false) {
$pos = strrpos($ip, ':');
$ipv6_part = substr($ip, 0, $pos);
$ipv4_part = substr($ip, $pos + 1);
return array($ipv6_part, $ipv4_part);
}
else {
return array($ip, '');
}
