Restrict registration by ip/net

Hello!

I need to do the same thing.
Is it possible?

I think it is not possible to restrict by IP who can send account registration requests.

A possible solution is:

1. Create a page in PHP that allows to register accounts.
2. That page in PHP creates the accounts in ejabberd using a method like ejabberdctl command line calls, or XML-RPC calls.
3. Disable in ejabberd the module mod_register
4. Configure your web server to restrict access to your page by IP
