After switching the default DNS server in Plesk from BIND to Microsoft DNS not all of the slave DNS servers configured in ‘Transfer Restrictions’ receive copies of DNS zones from the server.


Microsoft DNS doesn’t allow adding subnets to the transfer restrictions list (ACL), as such, 256 IP addresses from each subnet configured in Transfer restrictions in BIND will be added to MS DNS.


It is not recommended to allow transfers to all IPs from /8 and /16 networks (2^24 and 2^16 IP addresses) to DNS transfers as it may cause possible security issues. Consider using explicit restrictions for each individual slave server.
