## Name
*transfer* - perform (outgoing) zone transfers for other plugins.
*transfer* - perform zone transfers for other plugins.
## Description
This plugin answers zone transfers for authoritative plugins that implement `transfer.Transferer`.
This plugin answers zone transfers for authoritative plugins that implement
`transfer.Transferer`. Currently, no internal plugins implement this interface.
*transfer* answers full zone transfer (AXFR) requests and incremental zone transfer (IXFR) requests
Transfer answers full zone transfer (AXFR) requests and incremental zone transfer (IXFR) requests
with AXFR fallback if the zone has changed.
When a plugin wants to notify it's secondaries it will call back into the *transfer* plugin.
The following plugins implement zone transfers using this plugin: *file*, *auto*, *secondary*, and
*kubernetes*. See `transfer.go` for implementation details if you are a plugin author that wants to
use this plugin.
Notifies are not currently supported.
## Syntax
~~~
transfer [ZONE...] {
to ADDRESS...
to HOST...
}
~~~
* **ZONE** The zones *transfer* will answer zone transfer requests for. If left blank, the zones
are inherited from the enclosing server block. To answer zone transfers for a given zone,
there must be another plugin in the same server block that serves the same zone, and implements
`transfer.Transferer`.
* **ZONES** The zones *transfer* will answer zone requests for. If left blank,
the zones are inherited from the enclosing server block. To answer zone
transfers for a given zone, there must be another plugin in the same server
block that serves the same zone, and implements `transfer.Transferer`.
* `to` **ADDRESS...** The hosts *transfer* will transfer to. Use `*` to permit transfers to all
addresses. **ADDRESS** must be denoted in CIDR notation (e.g., 127.0.0.1/32) or just as plain
addresses. `to` may be specified multiple times.
* `to ` **HOST...** The hosts *transfer* will transfer to. Use `*` to permit
transfers to all hosts.
## Examples
See the specific plugins using this plugin for examples on it's usage.
