Ip

  • Ip()
  • Ip(string $range)
  • Ip(string $range, int $options)

Validates whether the input is a valid IP address.

This validator uses the native filter_var() PHP function.

v::ip()->assert('127.0.0.1');
// Validation passes successfully

v::ip('220.78.168.0/21')->assert('220.78.173.2');
// Validation passes successfully

v::ip('220.78.168.0/21')->assert('220.78.176.2');
// → "220.78.176.2" must be an IP address in the 220.78.168.0/255.255.255.255 range

Validating ranges:

v::ip('127.0.0.1-127.0.0.5')->assert('127.0.0.2');
// Validation passes successfully

v::ip('127.0.0.1-127.0.0.5')->assert('127.0.0.10');
// → "127.0.0.10" must be an IP address in the 127.0.0.1-127.0.0.5 range

You can pass a parameter with filter_var() flags for IP.

v::ip('*', FILTER_FLAG_NO_PRIV_RANGE)->assert('192.168.0.1');
// → "192.168.0.1" must be an IP address

If you want to validate IPv6 you can do as follow:

v::ip('*', FILTER_FLAG_IPV6)->assert('2001:0db8:85a3:08d3:1319:8a2e:0370:7334');
// Validation passes successfully
