+# 1. Add port info to hosts
+Re-use `hosts` setup and add domain and port information to each host
+```nix
+{
+    hostname = "overseerr";
+    ip = "192.168.0.105";
+    mac = "8E:21:7F:88:3A:83";
+    # new stuff
+    exposes = {
+        requests = {
+    port = 3000;
+            domain = "requests.xirion.net";
+            port = 3000;
+        };
+        ...
+    };
+}
+```
+which then can get translated to nginx config:
+```nix
+virtualHosts."requests.xirion.net" = proxy "http://192.168.0.105:80";
+```
+
+Ideally hosts should also be able to access their own host information more easily so
+that in service config one could use `thisHost.exposes.requests.port` or similar
+
+# 2. Authoritative nameserver
+Using the definitions from (1), we can then also build authoritative DNS records
+by folding over `hosts[i].exposes.requests.domain` and collating that with its realm (and therefore external IP)
+
+This also means I should probably put the external IP in some kind of meta block per realm.
+
+[dns.nix](https://github.com/kirelagin/dns.nix) seems to be a nice DSL for DNS stuff
