# whoami
|
|
|
|
## Name
|
|
|
|
*whoami* - returns your resolver's local IP address, port and transport.
|
|
|
|
## Description
|
|
|
|
The *whoami* plugin is not really that useful, but can be used for having a simple (fast) endpoint
|
|
to test clients against. When *whoami* returns a response it will have your client's IP address the
|
|
additional section as either an A or AAAA record.
|
|
|
|
The reply always has an empty answer section. The port and transport are included in the additional
|
|
section as a SRV record, transport can be "tcp" or "udp".
|
|
|
|
~~~ txt
|
|
._<transport>.qname. 0 IN SRV 0 0 <port> .
|
|
~~~
|
|
|
|
The *whoami* plugin will respond to every A or AAAA query, regardless of the query name.
|
|
|
|
If CoreDNS can't find a Corefile on startup this is the _default_ plugin that gets loaded. As such
|
|
it can be used to check that CoreDNS is responding to queries. Other than that this plugin is of
|
|
limited use in production.

## Examples
|
|
|
|
Start a server on the default port and load the *whoami* plugin.

|
|
|
~~~ corefile
|
|
. {
|
|
whoami
|
|
}
|
|
~~~
|
|
|
|
When queried for "example.org A", CoreDNS will respond with:
|
|
|
|
~~~ txt
|
|
;; QUESTION SECTION:
|
|
;example.org. IN A
|
|
|
|
;; ADDITIONAL SECTION:
|
|
example.org. 0 IN A 10.240.0.1
|

_udp.example.org. 0 IN SRV 0 0 40212
