Banning and whitelisting IP addresses | Communifire Documentation

Banning IP addresses can be useful for keeping your intranet friendly and free of harassment. Banning an IP address prevents a user from accessing your intranet from that particular IP address. This can be useful for preventing banned users from creating new accounts in attempts to get back into the intranet without permission.

How to Find a User's IP

To find a user's IP, the account must be active.

1. Click the gear icon > Manage People.
2. Search for the user.
3. For the user, click the gear icon > View Stats.
4. The User Activity page will open. Copy the IP address.

Ban IP

1. Click the gear icon > Manage People > Banned IPs.
2. Click Add IP.
3. Enter a Start IP Address and End IP Address. If you're banning a single IP address, enter the IP in both fields.
4. Enter a Description. The description can be viewed later by editing the banned IP.
5. Click Save.

When a banned IP address tries to access your intranet, they will see the message "Your IP has been banned".

Whitelisting IP addresses

An IP address is always a set of four numbers Each number can range from 0 to 255. So, the full IP addressing range goes from 0.0.0.0 to 255.255.255.255. To whitelist an IP address, admins can use the Banned IP feature to ban the full range of possible IP addresses except for a whitelisted set of IP addresses.

As an example, if you wanted to whitelist the IP address 168.212.226.204 and ban all other IP addresses, you could add two banned ranges:

1. 000.000.000.000 to 168.212.226.203 and
2. 168.212.226.205 to 255.255.255.255

Note: Banning IP ranges can cause issues with Integrations and Extensions, and should be done so with caution.
