Validate that all values passed are valid IP addresses,
regardless they are IPv4 or IPv6
Fail compilation if any value fails this check.
The following values will pass:
$my_ip = "1.2.3.4"
validate_ip_address($my_ip)
validate_ip_address("8.8.8.8", "172.16.0.1", $my_ip)
$my_ip = "3ffe:505:2"
validate_ip_address(1)
validate_ip_address($my_ip)
validate_ip_address("fe80::baf6:b1ff:fe19:7507", $my_ip)
The following values will fail, causing compilation to abort:
$some_array = [ 1, true, false, "garbage string", "3ffe:505:2" ]
validate_ip_address($some_array)
