Usage: drill name [@server] [type] [class]
<name> can be a domain name or an IP address (-x lookups)
<type> defaults to A
<class> defaults to IN
arguments may be placed in random order
Options:
-D enable DNSSEC (DO bit)
-T trace from the root down to <name>
-S chase signature(s) from <name> to a know key [*]
-V <number> verbosity (0-5)
-Q quiet mode (overrules -V)
-f file read packet from file and send it
-i file read packet from file and print it
-w file write answer packet to file
-q file write query packet to file
-h show this help
-v show version
Query options:
-4 stay on ip4
-6 stay on ip6
-a fallback to EDNS0 and TCP if the answer is truncated
-b <bufsize> use <bufsize> as the buffer size (defaults to 512 b)
-c <file> use file for rescursive nameserver configuration (/etc/resolv.conf)
-k <file> specify a file that contains a trusted DNSSEC key (DNSKEY|DS) [**]
used to verify any signatures in the current answer
-o <mnemonic> set flags to: [QR|qr][AA|aa][TC|tc][RD|rd][CD|cd][RA|ra][AD|ad]
lowercase: unset bit, uppercase: set bit
-p <port> use <port> as remote port number
-s show the DS RR for each key in a packet
-u send the query with udp (the default)
-x do a reverse lookup
when doing a secure trace:
-r <file> use file as root servers hint file
-t send the query with tcp (connected)
-d <domain> use domain as the start point for the trace
-y <name:key[:algo]> specify named base64 tsig key, and optional an
algorithm (defaults to hmac-md5.sig-alg.reg.int)
-z don't randomize the nameservers before use
[*] = enables/implies DNSSEC
[**] = can be given more than once
