-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Vitalie,
The timeouts depend on the exact roundtrip times as observed, and the nameservers for the domain. If you want to have a timeout in your software in case the resolution takes a long time, perhaps you want to use alarm(2) or another timeout mechanism (e.g. from libevent). Such as, use select(2) on the ub_fd() with the timeout of your choice. You can use ub_cancel() to tell libunbound that the result of this query is no longer needed.
