Use textareas and allow "one IP per line"

To improve the management of long IP lists, forms should use textareas (resizable?) with one IP address (in CIDR notation) per line. This is more consistent with Drupal core.

Currently, IP lists are semi-colon delimited and shown in a textfield so you can't see or edit them easily.

Original summary:

Hi,

Could a maxlength of 256 be added to the 'restrict role by IP' fields as I'm finding the fields to short for the number of IP's I need to add?

Thanks,

Richard
