DESCRIPTION
       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.

OPTIONS
       -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.

       --verbose
               Be verbose.

       --help  Display online help.

       --version
               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
               object.
               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.

NOTES
       Please  remember  that  whois.networksolutions.com by default will only
       search in the domains database. If you want to search for  NIC  handles
       you have to prepend a ! character. When you do this, the default server
       becomes whois.networksolutions.com.

       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
       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-
       ing.

FILES
       /etc/whois.conf

ENVIRONMENT
       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.

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

       WHOIS_SERVER
              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.

BUGS
       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
       dynamics strings library.

HISTORY
       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.  I also  added  support  for  the  protocol  extensions
       developed by David Kessens of QWest for the 6bone server.
