# erratic *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. ~~~ txt ._.qname. 0 IN SRV 0 0 . ~~~ 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 { drop AMOUNT } ~~~ * **AMOUNT** drop 1 per **AMOUNT** of the queries, the default is 2. ## Examples ~~~ txt .:53 { erratic { drop 3 } } ~~~ Or even shorter if the defaults suits you: ~~~ txt . { erratic } ~~~ ## Bugs Delaying answers is not implemented.
