SYNOPSIS

       drill [ OPTION ] name [ @server ] [ type ] [ class ]

DESCRIPTION

       drill  is a tool to designed to get all sorts of information out of the
       DNS. It is specificly designed to be used with DNSSEC.

       The name drill is a pun on dig. With drill you should be able get  even
       more information than with dig.

       The  arguments to drill may be placed in any order. If no arguments are
       given class defaults to 'IN' and type to 'A'. The  server(s)  specified
       in /etc/resolv.conf are used to query against.


       @server  Send  to  query to this server. If not specified use the name-
       servers from /etc/resolv.conf.


       type Ask for this RR type. If type is not given on the command line  it
       defaults  to  'A'. Except when doing to reverse lookup when it defaults
       to 'PTR'.


       name Ask for this name.


       class Use this class when querying.

SAMPLE USAGE

       drill mx miek.nl Show the MX records of the domain miek.nl


       drill -S jelte.nlnetlabs.nl
              Chase any signatures in the jelte.nlnetlab.nl domain.


       drill -TD www.example.com
              Do a DNSSEC  (-D)  trace  (-T)  from  the  rootservers  down  to
              www.example.com.


       drill -s dnskey jelte.nlnetlabs.nl
              Show the DNSKEY record(s) for jelte.nlnetlabs.nl. For each found
              DNSKEY record also print the DS record.

OPTIONS

       -D     Enable DNSSEC in the  query.  When  querying  for  DNSSEC  types
              (DNSKEY, RRSIG, DS and NSEC) this is not automaticly enabled.

       -Q     Quiet mode, this overrules -V.


       -f file
              Read the query from a file. The query must be dumped with -w.


       -i file
              read the answer from the file instead  from  the  network.  This
              aids in debugging and can be used to check if a query on disk is
              valid.  If the file contains binary data it is assumed to  be  a
              query in network order.


       -w file
              Write an answer packet to file.


       -q file
              Write the query packet to file.


       -v     Show drill's version.


       -h     Show a short help message.


   QUERY OPTIONS
       -4     Stay on ip4. Only send queries to ip4 enabled nameservers.


       -6     Stay on ip6. Only send queries to ip6 enabled nameservers.


       -a     Don't  try the next nameserver on SERVFAIL. The default is to do
              this.


       -b size
              Use size as the buffer size in the EDNS0 pseudo RR.


       -c     Use TCP/IP when querying a server, 'c' stands for connected.


       -k keyfile
              Use this file to read a (trusted) key from. When this options is
              given  drill tries to validate the current answer with this key.
              No chasing is done. When drill is doing a secure trace, this key
              will be used as trust anchor.


              Thus: -o CD, will enable Checking Disabled, which instructs  the
              cache to not validate the answers it gives out.


       -p port
              Use this port instead of the default of 53.


       -s     When encountering a DNSKEY print the equivalent DS also.


       -u     Use UDP when querying a server. This is the default.


       -w file
              write  the answer to a file. The file will contain a hexadecimal
              dump of the query. This can be used in conjunction with -f.


       -x     Do a reverse loopup. The type argument is not used, it is preset
              to PTR.
