# DNS in Headscale Headscale supports Tailscale's DNS configuration and MagicDNS. Please have a look to their KB to better understand what this means: - https://tailscale.com/kb/1054/dns/ - https://tailscale.com/kb/1081/magicdns/ - https://tailscale.com/blog/2021-09-private-dns-with-magicdns/ Long story short, you can define the DNS servers you want to use in your tailnets, activate MagicDNS (so you don't have to remember the IP addresses of your nodes), define search domains, as well as predefined hosts. Headscale will inject that settings into your nodes. ## Configuration reference The setup is done via the `config.yaml` file, under the `dns_config` key. ```yaml server_url: http://127.0.0.1:8001 listen_addr: 0.0.0.0:8001 private_key_path: private.key dns_config: nameservers: - 1.1.1.1 - 8.8.8.8 restricted_nameservers: foo.bar.com: - 1.1.1.1 darp.headscale.net: - 1.1.1.1 - 8.8.8.8 domains: [] magic_dns: true base_domain: example.com ``` - `nameservers`: The list of DNS servers to use. - `domains`: Search domains to inject. - `magic_dns`: Whether to use [MagicDNS](https://tailscale.com/kb/1081/magicdns/). Only works if there is at least a nameserver defined. - `base_domain`: Defines the base domain to create the hostnames for MagicDNS. `base_domain` must be a FQDNs, without the trailing dot. The FQDN of the hosts will be `hostname.namespace.base_domain` (e.g., _myhost.mynamespace.example.com_). - `restricted_nameservers`: Also known as Split DNS (see https://tailscale.com/kb/1054/dns/), list of search domains and the DNS you want to use for them.
