The new anycast resolver for
.dn42 runs on
fd42:d42:d42:53::1. Please see Hierarchical DNS for more information.
The information below is outdated.
(tl;dr) We have a TLD for dn42, which is
.dn42. The anycast resolver for
.dn42 runs on
DNS is build from whois database. So please edit your DNS-records there.
Below are several ways to use the
dn42 DNS service, from easiest to more challenging. The recommended method is the second one.
Please be aware that this method sends all your DNS queries (e.g.
google.com) to a random DNS server inside dn42. The server could fake the result and point you towards the russian mafia. They probably won't, but think about what you are doing. At the end of the day, your ISP could be evil as well, so it always boils down to a question of trust.
To do this, just use
fd42:d42:d42:53::1 as your resolver, for instance in
If you run your own resolver (
bind), you can configure it to forward dn42 queries to the anycast DNS resolver. See DNS forwarder configuration.
You may also want to configure your resolver to recursively resolve dn42 domains. For this, you need to find authoritative DNS servers for the
dn42 zone (and for the reverse zones). See services/dns/Recursive DNS resolver.
Finally, you may want to host your own authoritative DNS server for the
dn42 zone and the reverse zones. The zone files are built from the monotone repository: scripts are provided in the repository itself.
The root zone for
dn42. is built from the whois registry. If you want to register a domain name, you need to add it to the registry (of course, you also need one or two authoritative nameservers).
There is a monitoring process that checks to verify that registered domain names are configured and reachable within the network. If a network has been detected as inactive consistently for a month, it will be moved to an offline folder in the registry. This will disable it from being generated into the anycast dns and future health checks. To reactivate the domain it will have to be moved back from the dns-offline folder.
The health check results are emailed out each week to the mailing list.
Other networks are interconnected with dn42 (ChaosVPN, Freifunk, etc). Some of them also provide DNS service, you can configure your resolver to use it. See External DNS.
This is a new effort to build a DNS system that mirrors how DNS was designed to work in clearnet.
