Register IP – Multisite

Spam is one thing, but trolls and sock puppets are another. Sometimes people just decide they’re going to be jerks and create multiple accounts with which to harass your honest users. This plugin helps you fight back by logging the IP address used at the time of creation.

When a user registers, their IP is logged in the wp_usermeta under the signup_ip key. Log into your WP install as an Admin and you can look at their profile or the users table to see what it is. For security purposes their IP is not displayed to them when they see their profile.


Latest version: Download Register IP – Multisite v1.6.1 [zip]


No special activation needed.


Q. Why do some users say “None Recorded”?
A. This is because the user was registered before the plugin was installed and/or activated.

Q. Who can see the IP?
A. Admins and Network Admins.

Q. Does this work on MultiSite?
A. Yep!

Q. If this works on SingleSite why the name?
A. There’s already a plugin called “Register IP”, but it didn’t work on MultiSite. I was originally just going to make this a MultiSite-only install, but then I thought ‘Why not just go full bore!’ Of course, I decided that AFTER I requested the name and you can’t change names. So you can laugh.

Q. Does this work with BuddyPress?
A. It works with BuddyPress on Multisite, so I presume single-site as well. If not, let me know!

Q. This makes my screen too wide!
A. Sorry about that, but that’s what happens when you add in more columns.

Q. What’s the difference between MultiSite and SingleSite installs?
A. On multisite only the Network admins who have access to Network Admin -> Users can see the IPs on the user list.
