#### IP Filter

This filter allows you to manually blacklist or whitelist IP addresses. A comment coming from an IP address listed in the black list section will immediately be considered as junk. A comment coming from an IP address listed in the white list section will be considered as trusted and the other antispam filters won't process it.

To add an IP, first select the tab you want (Blacklist or Whitelist) and enter the IP address. The Global IP checkbox is available if you are a super administrator and will allow you to add the IP address to all the blogs of your Dotclear installation.

You can add IP addresses with a network mask to block or allow a range of IP addresses. For example:

- `127.0.0.0/255.0.0.0` or the abbreviated form `127/8` will recognize all the IP addresses like `127.xxx.xxx.xxx`
- `127.0.0.0/255.255.0.0` or the abbreviated form `127.0/16` will recognize all the IP addresses like `127.0.xxx.xxx`
- `127.0.0.0/255.255.255.0` or the abbreviated form `127.0.0/24` will recognize all the IP addresses like `127.0.0.xxx`
