This tab lets you configure IP address ranges and specify whether they are trusted, suspect or blocked (they can also be unknown).

Each range shows:

• The number of users created by visitors in that range
• The number of anonymous contact forms submitted (contact emails sent) by visitors in that range
• The number of times a user action has been blocked because the visitor was in a blocked range

Unknown IP ranges

b2evolution will automatically create unknown ranges if several users are created from within the same C class of IP addresses.

Every time a user account is created, we search if other users have already been created from the same C class (same first 24 bits of the IP address).

If that is the case, we either create an entry in this table with aipr_user_count = 2 or update it to a higher value.

Blocked IP ranges

Several actions will be blocked if a request (HTTP request) comes from a blocked IP range.

See Blocking actions from spammers.

Suspect IP ranges

When a user creates an account from a suspect range, the user account can automatically be put into a special group, which may have restricted permissions.

See System > Antispam > Settings > Suspect Users

This option can also be checked for each collection at Analytics > [Collection] > IPs > IP Ranges.
