I'm stuck back on Sierra because later OS X Server versions no longer include DNS.
The Server app is a bit limited and doesn't allow you to enter wildcards (perfectly acceptable in BIND which is what is running).
So I edit the NAMED records directly and enter the * records. Works fine, for a while.
Intermittently some process is overwriting the DNS records and removing the wildcard entries.
What is the proper way to adjust records so they don’t revert or have to be repeated manually?
