– Do you require zone transfers in to Azure DNS, or zone transfers out? Why?
We have a project to have many ***** on-premise but also in the cloud as possible. To do so, we need to be able to zone transfer the information from our Primary DNS server to the Secondary in the cloud
– Do you require AXFR or IXFR?
In fact, we require both AXFR and IXFR

Actually we are using the protocol GSS-TSIG, so with the same protocol or an equivalent
