You can anonymize IP addresses by following the steps below:

  1. Sign in to your account.
  2. Pick the website you're interested in from the drop down menu next to the "Help" tab.
  3. Click the "Settings" tab on the left hand side.
  4. Click the "Privacy Settings" tab.
  5. In the "Anonymize User IPs" section, flip the toggle to "Yes".
  6. Hit "Save".

This will anonymize all user's IP addresses by removing the last tuple. Note that IP addresses are automatically anonymized on all EU/EAA accounts.
