Well you can go to https://ednscomp.isc.org and click on "Test Your Servers Here”
which is what https://dnsflagday.net calls behind the scenes.  You will just need
to interpret the results as they apply to DNS flag day.  If you don’t want to go
there you can go to https://gitlab.isc.org and down load and compile the DNS
compliance tester and then run “genreport -i bind11 -e”. which is the actual test
code being run.

But hey you did do proper acceptance testing when you installed your DNS servers
and firewalls to ensure that they implemented the DNS protocol correctly and they
your firewalls don’t block well formed DNS queries (lots of them do by default).
