Antispam IP Address - Search

Good morning folks,
I have a questions we have a site which has a large list of users, we have noticed that some clients are creating multiple accounts and are using the Same IP address, currently there are over 8790+ users on the site.

We would like to make the 'moderate-users/searching' menu item able to search through the lists for and IP address, what we have discovered is that at present you cannot enable 'Searchable'

Error Message
"Cannot batch process row id 95 because: Calculated fields cannot be searchable!"

The only way this can be searched at present is to go to a page with the list active and user the browser search 'Ctrl F'
This is not very effective with over 200+ users as you cannot load them all on the screen at once without crashing the load time.

The CB AntiSpam IP Address field is not searchable as it either uses the ip address stored to a user at time of registration or the one in CB AntiSpam Log. You can search the CB AntiSpam log, but that's about it as far as searching by ip address. CB AntiSpam has duplicate registration protection feature you can enable though and will block duplicate registrations from same ip address.

Krileon,
We are touching base on this feature again now cause we have had a large number of duplicate accounts created and we have turned on the IP feature but it does not appear to be working correctly.

Current settings are;
Menu
Block Account - Enable
Block User - Enable
Block IP Address - Enable
Block Email Address - Enable
Block Email Domain - Disable
Whitelist User - Enable
Whitelist IP Address - Enable
Whitelist Email Address - Enable
Whitelist Email Domain - Disable

Block Reason = Our system has detected that you have too many failed registration attempts. Your IP Address has been logged and blocked for 1 Month.

What do you mean by it's not working correctly? Is it not blocking users? You setup the duplicate login limit to 10 so it's not going to do anything until an account has been logged into by more than 10 different ip addresses; that seams a bit generous. The below defaults are tested working fine to block duplicate logins.

Duplicates
Active Logins: 1
Block Method: Deny Login
Block Duration: +1 HOUR

Sharing
Share Limit: 10
Share Timeframe: -1 MONTH
Block Method: Logout Current Session
Block Duration: +1 HOUR

You probably don't need Auto Block. That's to stop failed login attempts and don't recommend it unless you've a lot of brute force attempts. You really should only need the Duplicates feature as it prevents more than 1 session for a single account. The below works pretty well for ensuring only 1 person can login to an account at a given time.

Duplicates
Active Logins: 1
Block Method: Logout Current Session
