The “IP Whitelist” plugin allows administrators to limit access to the WordPress dashboard by whitelisting specific IP addresses. It’s intended to enhance security by restricting access to only trusted sources.

This plugin is designed to safely allow bbcode shortcodes and other 
safe shortcodes to be embedded in bbpress topics and replies and also 
blog comments. You don’t wan’t users entering shortcodes such as 
[bbp-login] in the middle of their reply.
It doesn’t actually implement the shortcodes though, 
for that you need a separate plugin. I recommend my own bbPress2 
BBCode plugin, as this is fully whitelist aware, in that it also 
parses the contents of the shortcodes, so [b][bbp-login][/b] also 
gets parsed for safety. Something that doesn’t happen with non 
whitelist aware shortcode plugins.

This plugin adds creates a whitelist of shortcode tags that can be applied to comments, bbPress and BuddyPress.
