Hello,

If you're looking at this page, you're probably wondering about the BitTorrent tracker running on this host.

It's operated by Desync Corporation in the United States as a public service to the Internet community. It is an open tracker that allows any and all announcements from any address. It supports IPv4 and IPv6 torrents (separately).

The only information we maintain is a list of peers that are associated with each hash, which is the minimum required to facilitate the tracker service. Peer information is never written to disk and no logs are kept. We do not have any content or even any knowledge of what content is represented by a given hash. For more information, you can read the Wikipedia article on BitTorrent trackers.

Please be aware that we respond to valid DMCA requests as required by law by prohibiting individual hashes. You can download a list of the hashes that we have been asked to block.

We use the seriously awesome Opentracker software. If you have any questions or concerns about our tracker, you may contact us at root@desync.com.

We changed the way the address source limits work and, as a result, the peer graph is nice and smooth again. Only spammers who bomb us with fake announces should be effected, but if you're suddenly having trouble connecting, we'd be interested in hearing from you. On that note, most of the fake peers these days come from LeaseWeb and SoloGigabit, the same places the publicbt and openbittorrent trackers are hosted. That's strange, right?

If you notice that massive spike in IPv6 peers over there, you may be thinking, "hey IPv6 is really taking off!" Unfortunately, you'd be wrong (for now). It seems that a certain type of company with a certain type of software that creates a lot of fake annoucements suddenly switched from IPv4 to IPv6. The source of these fake peers is 2404:3600:0:a:4d2e:7605:4249:8af. That IPv6 space belongs to a company called Obtrix, who ironically rents seedboxes.

FAQs

Q: Does port 80 work?

A: Yes.

Q: Why can't I connect?

A: You may have tripped our connection rate limiting or other protection. We employ a number of techniques to minimize the load from abusive peers (or evil companies posing as peers). You can either contact us with your source address or you can wait 24-48 hours.

Q: Is 2002::/16, aka 6to4 blocked?

A: Yes. We send a TCP RST and your client should immediately retry using IPv4. Because of the short-sighted design of the BitTorrent™ protocol, IPv4 and IPv6 peers must be separate. Since the people using 6to4 don't usually know it and almost never have native IPv6 connectivity, they're much better off using the IPv4 tracker. Conversely, people with real IPv6 connectivity are much better off without people on slow 6to4 tunnels clogging up their peer slots.

Q: Why is all your address space listed in every blacklist?

A: Because the people who run these blacklists are, for the most part, not technically able to determine which networks pose a threat. They blacklist networks without the benefit of technical expertise, visibility or merit. This is apparently a common problem. We asked one of them to remove us, but got their standard response.

You're stupid. Trackers are obsolete now that
magnet links have caught on. Using dodgy trackers
such as yours are an unnecessary and foolish risk
to take.

If you're unaware that anti-p2p companies run
their own trackers, you're very very ignorant. 

Being insulting and showing a bad attitude may get
you somewhere with the people in your little
world, but I can assure you that with us and
people in general civility is a much better tact
to take. Go fornicate yourself in the least
comfortable manner possible. Worst of luck to you
and have a lousy life.
