This may be completely unrelated, but on our LANs we use Cisco switches to issue DHCP and despite all the correct records, we regularly see both A and PTR records haven't been correctly registered.
Our research led us to find that this is a common issue with no comprehensive solution we could find so our main applications rely on certificates now instead of hostname where possible.
Obviously this has other benefits but isn't always possible so I'm following this thread inc there is a solution that might help us! 😉
