This plugin adds a new “Plugins” tab to the site edit screen where you can enable or disable plugins for this website. You may enable/disable one at a time or per bulk action. The site admin will only see plugins that are enabled for his site or for the entire network. He still can decide if he wants to activate it or not.
Finally you’ll be able to install plugins that do not show to every single website in your multisite network!
<h3>Enable/Disable plugins for selected sites</h3>
<ol>
<li>Visit Network Admin > Sites and click on the Edit link of one site.</li>
<li>Select the Plugins tab.</li>
<li>Click on the Enable/Disable link beneath each plugin name to enable/disable it for this site or</li>
<li>Select several plugins by checking the corresponding check boxes or all plugins by checking the checkbox in the table header an choose Enable or Disable form the Bulk actions dropdown menu. Then click Apply.</li>
</ol>
You cannot disable a plugin for a site as long as it is activated there.

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.
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 a user’s own IP is not displayed to them when they look at their own profile.

<h3>Privacy Notes</h3>
This plugin adds additional data to a new user’s <code>wp_usermeta</code> data under the <code>signup_ip</code> key. This data is directly tied to the user account, and is only editable via the database. Should a user account be deleted from the site, the data will be automatically deleted.
No external data is transmitted, it all stays on your install.

Register IPs

Does exactly waht it says

When a new user registers, their IP address is logged. Supports multisite and single site!
