This middleware allows playing with responses. Only one type is implemented: it allows you to drop queries. I.e. withhold the response from the client.

*erratic* is a middleware useful for testing client behavior. It returns a static response to all
|
|
queries, but the responses can be delayed by a random amount of time or dropped all together, i.e.
|
|
no answer at all.

|
|
The *erratic* middleware will respond to every A or AAAA query. For any other type it will return
|
|
a SERVFAIL response. The reply for A will return 192.0.2.53 (see RFC 5737), for AAAA it returns
|
|
2001:DB8::53 (see RFC 3849).

## Syntax

~~~ txt
|
|
erratic {

## Examples

erratic {

Or even shorter if the defaults suits you:
|
|
