Dns dynamically updating bind

Normally incremental zone transfers are only possible when used in conjunction with Dynamic DNS (DDNS).

Many people like to be cautious in case the default mode changes.

allow-update-forwarding defines a match list, for instance, IP address(es) that are allowed to submit dynamic updates to a 'slave' sever for onward transmission to a 'master'.

This statement may be used in zone, view or an options clause.

This statement is mutually exclusive with update-policy and applies to master zones only.
