# Original DNS (deprecated)

This information is now deprecated. Please check New DNS for the current architecture.

(tl;dr) We have a TLD for dn42, which is `.dn42`. The anycast resolver for `.dn42` runs on `172.20.0.53` and `fd42:d42:d42:54::1`.

DNS is build from whois database. So please edit your DNS-records there.

## Using the DNS service

Below are several ways to use the `dn42` DNS service, from easiest to more challenging. The recommended method is the second one.

### Using the anycast resolver directly

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 `172.20.0.53` or `fd42:d42:d42:54::1` as your resolver, for instance in `/etc/resolv.conf`.

### Forwarding `.dn42` queries to the anycast resolver

If you run your own resolver (`unbound`, `dnsmasq`, `bind`), you can configure it to forward dn42 queries to the anycast DNS resolver. See DNS forwarder configuration.

### Recursive resolver

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.

### Building the dn42 zones from the registry

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.

## Register a `.dn42` domain name

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).

## DNS services for other networks

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.

## Old Hierarchical DNS

This is a new effort to build a DNS system that mirrors how DNS was designed to work in clearnet.
