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.

I'll have to look into CIDR to properly use it but I like the idea. Instead of blocking the rest of the world I can allow specific regions.

I've no idea what I could use it for, but it's a nice idea

Hm, I can add also field with denied cidr, so you will be able to deny some cidr and(or) allow some cidr...

Italy have many ISP's, so you want to block/allow them all or only some of them ? If all then there will be many records with many VLSM/CIDR regions...
