-u Use UDP instead of TCP. No retries are attempted.
-n Do not wait for the answer.
-s Use SSL.
-h Print program usage.
-f ipaddr[@port]
Specify the server to send the queries to. If not specified localhost (127.0.0.1) is used.

$ unbound-streamtcp -f 192.168.1.1 www.example.com SOA IN
$ unbound-streamtcp -f 192.168.1.1@1234 153.1.168.192.in-addr.arpa. PTR IN
