[nsd-users] how do I add an SVCB record to NSD

[Jeroen Koekkoek]

Hi Peter,

SVCB records, or any other kind of record, should be added to your zone
file. https://nsd.docs.nlnetlabs.nl/en/latest/zonefile.html should give
you a decent example of how such a file should look. As for how to add
SVCB records, the svcb test can probably shed some light:
https://github.com/NLnetLabs/nsd/blob/master/tpkg/svcb.tdir/svcb.success-cases.zone.

Hope that helps.
