                 [-b bufsize] [-t timeout] [-n] [-l limit] [-f family] [-1]
                 [-i interval] [-r arraysize] [-u unit] [-H histfile]
                 [-T qps] [-e] [-D] [-R] [-c] [-v] [-h]
  -d specifies the input data file (default: stdin)
  -s sets the server to query (default: 127.0.0.1)
  -p sets the port on which to query the server (default: 53)
  -q specifies the maximum number of queries outstanding (default: 20)
  -t specifies the timeout for query completion in seconds (default: 5)
  -n causes configuration changes to be ignored
  -l specifies how a limit for how long to run tests in seconds (no default)
  -1 run through input only once (default: multiple iff limit given)
  -b set input/output buffer size in kilobytes (default: 32 k)
  -i specifies interval of intermediate outputs in seconds (default: 0=none)
  -f specify address family of DNS transport, inet or inet6 (default: any)
  -r set RTT statistics array size (default: 50000)
  -u set RTT statistics time unit in usec (default: 100)
  -H specifies RTT histogram data file (default: none)
  -T specify the target qps (default: 0=unspecified)
  -e enable EDNS 0
  -D set the DNSSEC OK bit (implies EDNS)
  -R disable recursion
  -c print the number of packets with each rcode
  -v verbose: report the RCODE of each response on stdout
