Dear Tony,
Yes, the CARNet network guys have replied with an email acknowledging
the have corrected the bug in configuration ;-)
They thanked for the pointer to the actual bug.
I just tested the settings from three available servers (though all in
.hr domain), and it works now like it never worked before! :-) So, this
is finally the culprit ... If it either completely worked or completely
didn't, we'd probably think of it before ...
My conclusion now is that the next step would be to make them (reverse
PTRs) visible globally. So far, I am only seen from two DNS servers in
France and one in Brazil:
So, far, only my main building's server is seen in reverse PTR maps
globally:
Thanks, again. You have helped a great deal!
This will certainly improve the reliability of our service to the next
step (global visibility, so anyone could "see" us in logs with our
hostnames and report a problem globally.
Kind regards,
Mirsad

I have tried to verify your findings, but I've found something awkward:
Something has changed, because earlier I got:
; <<>> DiG 9.10.6 <<>> soa 192/27.186.198.193.in-addr.arpa @193.0.9.6
;; global options: +cmd

and now instead I get a referral:

And the SOA serial number for 198.193.in-addr.arpa has bumped to
2021122901.
The actual delegation that was missing was for 186.198.193.in-addr.arpa,
not the delegation for your zone 192/27.186.198.193.in-addr.arpa
This error was partially hidden because of the shared carnet.hr
nameservers.
Tony.
