Miscellaneous Hacks - Allow registration only from specified CIDR/IP(s) + include exceptions

Mod was updated to the 1.2.1 version.

With using "Allow registration only from specified CIDR/IP(s)" plugin, you can allow registration on your forum only from specified CIDR(NetMask) region(s), like (192.168.1.0/24) or from specified IP addresses (like 192.168.1.1 and e.t.c.). Also you can allow all subnetworks and make an exception for others (ban them) by entering them into exceptions list (check example in the screenshot).

This modification was created using Jonavon Wilcox's PHP functions.

If you want to allow some subnetwork, but you don't know how to write it in CIDR formatting, then you can use for that simple CIDR/VLSM calculator.

If you don't know what means CIDR/VLSM, you can read this article on Wiki - CIDR.

Product was tested on VB 4.0.1, but it also must works on VB 3.x.x - 4.x.x.

Options screenshot :

As we can see from this screenshot, I am allowed all subnetworks (0.0.0.0/1,128.0.0.0/1) and denied only 192.168.1.0/24 subnetwork. But I also used IP exception list and allowed "192.168.1.3" IP adress, which is in denied subnetwork.

Error message :

Installation :

Ok, I am attached list (Italy_CIDR_VLSM.txt) of all Italian net-masks, written in CIDR/VLSM formatting.

First of all - you must delete all others allowed CIDRs/NetMasks which is in allowed list after plugin installation. Then you can open attached txt file with notepad, press Ctrl+A (to select all ) and then you can paste it in "Allowed Sub-Networks (CIDR regions)" plugin field.

All Italian IP ranges I am get - there.

For future, you can convert IP ranges into CIDR formatting using Range_to_CIDR.php file, which I am attached to this post too (when it will be needed, you can upload php file to your site and then go to it via web-browser).
