The biggest differences are that with master-slave you do not need anything but
tcp/53 and udp/53 open between the servers (both ways), it can interoperate
with other DNS server products. There is no transport security implied other
than provided by TSIG. You also need to do serial number management to cause
Native replication is backend-specific and all limitations and benefits are
of the backend in question. F.ex. if you use mysql replication, you get near
instant changes in your slaves. No serial number management is required.
