This module does not support dynamic records.
See the /script/ directory for some tools to help with the development process. They generally follow the Script to rule them all pattern. Most useful is ./script/bootstrap which will create a venv and install both the runtime and development related requirements. It will also hook up a pre-commit hook that covers most of what's run by CI.
There is a docker-compose.yml file included in the repo that will set up a Bind9 server with AXFR transfers and RFC 2136 updates enabled for use in development. The secret for the server can be found in docker/etc/bind/named.conf.
