Mostly all high level trackers allow seeding from 3 different location (mean IP) maximum but torrents should be different (which already mentioned).
Concept behind allowing 3 different location(IP) is that member can use seedbox for adding large torrent/ recently added to create buffer, 2nd can be use download needful torrents from his home location & 3 rd one will be helpful if member gonna migrate seedbox or bought another storage box.
Some exception tracker are FileList & Chinese trackers. Just read their seeding rules before going for it
