 ## Future plans
 
-- Also generate DHCP server configurations
+- Automate serial generation
 - Build and verify with CI/CD
 - Automatically push updated configurations to the DNS server
-- Replace dns.nix with homemade zonefile generators to make them more human readable
-- Host-customizable TTL (e.g. for moving a CNAME around when replacing a service/server)
+    - Also generate DNS server configuration files
+        - [NSD](https://nlnetlabs.nl/projects/nsd/about/), included in OpenBSD
+        - [Bind9](https://www.isc.org/bind/), common alternative
+- Per-record or per-host customizable TTL (e.g. for moving a CNAME around when replacing a service/server)
+- Improve dns.nix or replace it with a homemade zonefile generator to make the output more human readable
