Question 1

What is a torrent tracker?

Accepted Answer

A torrent tracker is a server that coordinates BitTorrent peers. When you open a .torrent file or magnet link, your client contacts the tracker to ask 'who else has this file?' — the tracker responds with a list of peer IPs so your client can connect and start downloading.

Question 2

Do I still need trackers if magnet links use DHT?

Accepted Answer

Yes. DHT and PEX are useful fallbacks, but trackers are still the fastest way to bootstrap peer discovery — especially on fresh torrents or behind restrictive networks where DHT is blocked. Adding extra trackers reliably speeds up downloads.

Question 3

What's the difference between a public and private tracker?

Accepted Answer

Public trackers are open URLs anyone can announce to (e.g. opentrackr.org). Private trackers require an account and enforce ratio rules, but offer much higher speeds, better retention, and curated content.

Question 4

Are torrent trackers legal?

Accepted Answer

Trackers themselves are legal — they only coordinate peer connections and don't host files. What's regulated is the underlying content being shared. Using a VPN protects your IP from being logged by anyone joining the swarm.
