Hello Jacob,
I did this :
addAction(
NotRule (
OrRule {QTypeRule(DNSQType.A), QTypeRule(DNSQType.AAAA)}
),
AllowAction()
)
And it works as expected :
> showRules()
# Name Matches Rule
Action
0 0 !((qtype==A) || (qtype==AAAA))
allow
Thanks for your help
Regards

With dnsdist 1.4 (as far as I remember) those names for the various query types
changed, so dnsdist.ANY became DNSQType.ANY.
For your particular case of only wanting to serve A and AAAA records I would
probably just do (untested):
addAction(
NotRule(OrRule({QTypeRule(DNSQType.A),QTypeRule(DNSQType.AAAA)})),
RCodeAction(DNSRCode.REFUSED))
With all the warnings that Stephane already gave you about why this is a bad
idea.
You can replace RCodeAction(DNSRCode.REFUSED) with DropAction() if you don't
even want to reply with a REFUSED response.
Best regards,
Jacob
