# nsid
|
|
|
|
*nsid* add an identifier of this server to each reply.
|
|
|
|
This plugin implements RFC 5001 and adds an EDNS0 OPT resource record to replies that uniquely
|
|
identifies the server. This can be useful in anycast setups to see which server was responsible for
|
|
generating the reply and for debugging.
|
|
|
|
## Syntax
|
|
|
|
~~ txt
|
|
nsid [DATA]
|
|
~~
|
|
|
|
**DATA** is the string to use in the nsid record.
|
|
|
|
If **DATA** is not given, the host's name is used.
|
|
