IP address fields

This provides a field for storing an IP address or range.

The shorthand widget allows a user to enter the values in any of the following formats:


* example.com
* 10.10.10.10
* 10.10.10.*
* 10.10.10.0 - 10.10.12.255
* 10.10.10.10-20

The CIDR widget allows CIDR inputs only:


* 10.10.10.10/32

Drupal 7 version The addresses are stored internally as a long, this allows you to do network computations quickly (e.g. is 10.10.10.10 within the range 10.10.10.0 - 10.10.10.50).

This code will find any user entities that have an IP range which includes the visitors current IP address.

$visitor_addr = ip2long($user->hostname); $query = new EntityFieldQuery(); $result = $query ->entityCondition('entity_type', 'user') ->propertyCondition('status', 1) ->fieldCondition('field_yourfieldname', 'start', $visitor_addr, '<=', 0) ->fieldCondition('field_yourfieldname', 'end', $visitor_addr, '>=', 0) ->execute();
