+# DNS
+
+The Domain Name System (DNS) is a naming system for computers or other resources
+connected to a network.
+It associates various information with domain names.
+
+## Server
+
+A server can be setup via docker with the [ventz image](./docker-images/ventz_-_bind.md)
+
+## Records
+
+### A record
+
+A (address) records map hostnames to an IP.
+Its basic structure is:
+
+```txt
+name.        A      IP
+```
+
+Where `name` is the domain to map the `IP` to and `A` is the constant for
+the type of the record.
+
+### CNAME record
+
+CNAME (canonical name) records map one domain name to another.
+Its basic structure is:
+
+```txt
+name.        CNAME  value.
+```
+
+Where `name` is the domain to map the `value` (another domain) to and `CNAME` is
+the constant for the type of the record.
+
+### SRV record
+
+Service (SRV) records define the port and hostname for specified services.
+Its basic structure is:
+
+```txt
+_service._proto.name. TTL class SRV priority weight port target
+```
+
+Where `_service` is the service name, `_proto` is the used protocoll (TCP/UDP),
+`name` is the domain name to assign to, `TTL` is the DNS time to live, `class`
+always is `IN`, `SRV` is the constant for the type of the record, `priority` is
+the priority of the target host, `weight` is the relative weight for records
+with the same priority, `port` is the port on that the service can be found and
+`target` is the canonical hostname of the server.
+
+Note that you need to create an A if you bind a service to a `name` that doesn't
+already have one.

+### Link Minecraft to a subdomain
+
+To link Minecraft to one of your subdomains you need to add a [DNS](./dns.md)
+SRV-record:

+name: mine (or alternative subdomain)
+service: _minecraft
