ToxDNS is a tox ID-to-name mapping service. It allows users to shorten their regular, somewhat long, Tox IDs, with short and readable IDs, that closely resemble the format of an email address. An example of a ToxDNS service in use is, Which when added, resolves to the full ID (56A1ADE4B65B86BCD51CC73E2CD4E542179F47959FE3E0E21B4B0ACDADE51855D34D34D37CB5).

ToxDNS servers are federated, they are each run by their individual operators and their databases are stored online. This can, but doesn't necessarily, compromise your privacy, but really it's simple to minimize the risk so that it's nearly nonexistent.

ToxDNS is considerate to be deprecated. It's advised against using it as versions 1 and 2 of ToxDNS are insecure, and barely any client supports version 3.

It's also planned that libtoxdns would be removed from TokTok's toxcore repository in one of the following major/minor version ticks.

What you might want to know about ToxDNS

Some people have some concerns about how ToxDNS services could be used maliciously, mismanaged, or exploited as a single point of failure in order to deny a person the ability to look up the ID they want. Hopefully I can address those concerns here.

Impersonating a user(MITM) by switching the Tox ID associated with the username: If someone compromised your account on a ToxDNS Service or a server hosting ToxDNS records, they might be able to replace the Tox ID associated with the username. New users looking up a Tox ID using the compromised username would be directed to the wrong Tox ID. To minimize the chance of such a thing occurring, use a long, unique, random password for your ToxDNS account, and set the ID to be unchangable if the server supports it. This will not connect you with your intended friend and it does not give anyone access to your private key or any current or previous chat sessions keys.

Malicious Service Operator gathering metadata on Tox ID's as they are registered: A malicious site operator could keep some information about the users of the ToxDNS service as they register by retrieving that information from their browsing session. This could be used to correlate the ID to the IP address they used to register the ID with the ID and the email. If this concerns you, then sign up for the service via a reliable Onion Router for browsing the Web like Tor.

Denial of Service against a ToxDNS Service: If someone denies users access to the ToxDNS service they wish to use to lookup an ID, then they will not be able to look up ID's at that service. If this is a concern, you might join multiple ToxDNS services, host your own ToxDNS service, or distribute your whole Tox ID in text form or using a ''tox:'' link.

It should be noted that none of these area actually problems with ToxDNS itself. The first two are malicious activities that could be undertaken on a server, the third is just somebody taking a site down or blocking access to a site.

ToxDNS Services

As of yet, there is no official ToxDNS service. All services listed here are run by volunteers, use at your own risk.

Run your own

Don't want to trust a third party service? Want to use your own cool domain? Or want to contribute by hosting your own public service? You can quickly and easily install a ToxDNS service to run on your own server!

Some of the many open-source ToxDNS services include:
