[nsd-users] Why doesn't UDP cause UDP?

Hi Paul,

Previously, NSD always made his IXFR requests over UDP.
Since 3.2.0, we default to IXFR/TCP.
The UDP option is too still make IXFR/UDP requests.
We strongly recommend to use TSIG if you use IXFR/UDP.

NSD will still try to AXFR the zone with TCP, if the zone's current
serial is 0, or if the master server does not implement IXFR.

Best regards,

Matthijs
