Function type:
Ruby 3.x API

Overview

validate_ip_address() ⇒ Any

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)

Returns:

  • (Any)
