How to show the ip address in revision listing?
You could do this using rules and views.
First to create the rule:


  
  Create a text field named ip_address
  Manage display: make the field hidden
  Use Display Suite or a custom hook (or even CSS) to hide the field when filling out the form
  Create a Rule on event "Before saving content"
  Set a condition of content type: your content type
  Set a condition of Data comparison: [node:is-new], Data value: True (check the checkbox)
  Set an action of Set a data value, and set the field to be:
  PHP Code:
  


&lt;?php
  print ip_address();
?&gt;


Above taken from here: Get IP address of submitter

For your purposes the 6th bullet (your rule condition) can be set-up like this:


And for the final action (7th bullet) if you don't want to use the php you can first add and action


  'Add a variable' -> Value IP Address 


and use that as in a second 'set a data value' action...

Now you can create a view that displays in a table format the fields 'Content Title' 'Revision Log' (i'm guessing this is what the operations column is recording?) and 'IP_Address', sorted by 'Node revision ID (desc)', or similar....

As it stands I am aware that this answer might not work for multiple revisions, rather only displays the IP for the latest revision. I imagine that when setting up your initial (hidden) IP_address field if you allow multiple values the rule will simply add values rather than over-write them. Maybe someone else on here has guidance on that...
