       whois searches for an object in a RFC 3912 database.

       This version of the whois client tries to guess the right server to ask
       for the specified object. If no guess can be made it  will  connect  to
       whois.networksolutions.com  for  NIC handles or whois.arin.net for IPv4
       addresses and network names.

       -h HOST, --host HOST
               Connect to HOST.

       -H      Do not display the legal disclaimers some  registries  like  to
               show you.

       -p, --port PORT
               Connect to PORT.

               Be verbose.

       --help  Display online help.

               Display client version information.

       Other  options  are  flags  understood by whois.ripe.net and some other
       RIPE-like servers:

       -a      Also search all the mirrored databases.

       -b      Return brief IP address ranges with abuse contact.

       -B      Disable object filtering. (Show the e-mail addresses.)

       -c      Return the smallest IP address range with a reference to an irt

       -d      Return the reverse DNS delegation object too.

               Search  updates  from  SOURCE  database  between FIRST and LAST
               update serial number. It's useful to obtain Near Real Time Mir-
               roring stream.

       -G      Disable grouping of associated objects.

       -i ATTR[,ATTR]...
               Search  objects having associated attributes. ATTR is attribute
               name.  Attribute value is positional OBJECT argument.

       -K      Return  primary  key  attributes  only.  Exception  is  members
               attribute  of  set  object  which  is  always returned. Another
               exceptions are all attributes of objects organisation,  person,
               and role that are never returned.

       -l      Return the one level less specific object.

       -L      Return all levels of less specific objects.

       -m      Return all one level more specific objects.

       -M      Return all levels of more specific objects.

       -q KEYWORD
               Return  list  of  keywords  supported by server. KEYWORD can be
               version for server version, sources for list  of  source  data-
               bases, or types for object types.

       -r      Disable recursive look-up for contact information.

       -R      Disable  following  referrals and force showing the object from
               the local copy in the server.

       -s SOURCE[,SOURCE]...
               Request the server to search for objects mirrored from SOURCES.
               Sources  are  delimited  by comma and the order is significant.
               Use -q sources option to obtain list of valid sources.

       -t TYPE Return the template for a object of TYPE.

       -T TYPE[,TYPE]...
               Restrict the search to objects of TYPE. Multiple types are sep-
               arated by a comma.

       -v TYPE Return the verbose template for a object of TYPE.

       -x      Search for only exact match on network address prefix.

       When  querying  the  Verisign  gTLDs (e.g. .com, .net...) thin registry
       servers for a domain the program will automatically prepend the  domain
       keyword  to only show domain records.  The nameserver or registrar key-
       words must be used to show other kinds of records.

       When querying whois.arin.net for IPv4 or IPv6 networks, the  CIDR  net-
       mask length will be automatically removed from the query string.

       When querying whois.nic.ad.jp for AS numbers, the program will automat-
       ically convert the request in the appropriate format, inserting a space
       after the string AS.

       When  querying  whois.denic.de for domain names and no other flags have
       been specified, the program will automatically add the flag -T dn.

       When querying whois.dk-hostmaster.dk for  domain  names  and  no  other
       flags  have been specified, the program will automatically add the flag

       RIPE-specific command line options are ignored when  querying  non-RIPE
       servers.  This  may  or  may not be the behaviour intended by the user.
       When querying a non-standard server, command line options which are not
       to  be  interpreted by the client should always follow the -- separator
       (which marks the beginning of the query string).

       If the /etc/whois.conf configuration file exists, it will be  consulted
       to  find  a  server  before applying the normal rules. Each line of the
       file should contain a regular expression  to  be  matched  against  the
       query  text and the whois server to use, separated by white space.  IDN
       domains must use the ACE format.

       The whois protocol does not specify an encoding  for  characters  which
       cannot be represented by ASCII and implementations vary wildly.  If the
       program knows that a specific server uses a certain encoding, if needed
       it  will  transcode  the server output to the encoding specified by the
       current system locale.

       Command line arguments will always be interpreted  accordingly  to  the
       current  system locale and converted to the IDN ASCII Compatible Encod-


       LANG   When querying whois.nic.ad.jp and whois.jprs.jp English text  is
              requested  unless  the LANG or LC_MESSAGES environment variables
              specify a Japanese locale.

              A list of options which will be evaluated before the ones speci-
              fied on the command line.

              This  server  will  be queried if the program cannot guess where
              some kind of objects are located. If the variable does not exist
              then whois.arin.net will be queried.

       The program may have buffer overflows in the command  line  parser:  be
       sure to not pass untrusted data to it.  It should be rewritten to use a
       dynamic strings library.

       This program closely tracks the user  interface  of  the  whois  client
       developed at RIPE by Ambrose Magee and others on the base of the origi-
       nal BSD client.
