Any updates here? Did you have the chance to reproduce this with at 
least stable, i.e. v252. Even better would be, if you can try with v254 
from bookworm-backports.

So far I failed to reproduce the issue with the given information.

$ host 54.49.125.74.in-addr.arpa
Host 54.49.125.74.in-addr.arpa not found: 3(NXDOMAIN)

That is all I get.

Michael
