I run 7.5.6p2 and need a litte suggestion how to change the Admin Panel. In the user managment approve queue I can see the register IP-address but it seems that the field is to short to handle the full IPv6 address. I close the automatic registration due lot of spambots and verify all registrations manually. So I need the full address to sort out some countrys.
Found a easy was to fix it. Go to phpmyadmin, search any table which blelongs to ip-address and change it from varchar 15 to varchar 40. No further chances needed. If I remeber right you habe to change 5 tabels.
