NAME

Net::Whois::Raw - Perl extension for unparsed raw whois information

SYNOPSIS

  use Net::Whois::Raw;
  
  $s = whois('perl.com');
  $s = whois('funet.fi');
  $s = whois('yahoo.co.uk');

  $OMIT_MSG = 1; # This will attempt to strip several known copyright
                messages and disclaimers sorted by servers.
                Default is to give the whole response.

  $OMIT_MSG = 2; # This will try some additional stripping rules
                if none are known for the spcific server.

  $CHECK_FAIL = 1; # This will return undef if the response matches
                one of the known patterns for a failed search,
                sorted by servers.
                Default is to give the textual response.

  $CHECK_FAIL = 2; # This will match against several more rules
                if none are known for the specific server.

  $CACHE_DIR = "/var/spool/pwhois/"; # Whois information will be
                cached in this directory. Default is no cache.

  $CACHE_TIME = 24; # Cache files will be cleared after not accessed
                for a specific number of hours. Documents will not be
                cleared if they keep get requested for, independent
                of disk space. Default is not to clear the cache.

  $USE_CNAMES = 1; # Use whois-servers.net to get the whois server
                name when possible. Default is to use the 
                hardcoded defaults.


  $TIMEOUT = 10; # Cancel the request if connection is not made within
                a specific number of seconds.

  Note: as of version 0.21, extra data will be loaded only if the
  OMIT_MSG or CHECK_FAIL flags were used, in order to reduce memory usage.

DESCRIPTION

Net::Whois::Raw queries NetworkSolutions and follows the Registrar: answer for ORG, EDU, COM and NET domains. For other TLDs it uses the whois-servers.net namespace. ($TLD.whois-servers.net).

Setting the variables $OMIT_MSG and $CHECK_FAIL will match the results against a set of known patterns. The first flag will try to omit the copyright message/disclaimer, the second will attempt to determine if the search failed and return undef in such a case.

IMPORTANT: these checks merely use pattern matching; they will work on several servers but certainly not on all of them.

CREDITS

Fixed regular expression to match hyphens. (Peter Chow, peter@interq.or.jp)

Added support for Tonga TLD. (.to) (Peter Chow, peter@interq.or.jp)

Added support for reverse lookup of IP addresses via the ARIN registry. (Alex Withers awithers@gonzaga.edu)

This will work now for RIPE addresses as well, according to a redirection from ARIN. (Philip Hands phil@uk.alcove.com, Trevor Peirce trev@digitalcon.ca)

Added the pattern matching switches, (Walery Studennikov despair@sama.ru)

Modified pattern matching, added cache. (Tony L. Svanstrom tony@svanstrom.org)

CLARIFICATION

As NetworkSolutions got most of the domains of InterNic as legacy, we start by querying their server, as this way one whois query would be sufficient for many domains. Starting at whois.internic.net or whois.crsnic.net will result in always two requests in any case.

NOTE

Some users complained that the die statements in the module make their CGI scripts crash. Please consult the entries on eval and die on perlfunc about exception handling in Perl.

LEGAL

Notice that registrars forbid querying their whois servers as a part of a search engine, or querying for a lot of domains by script. Also, omitting the copyright information (that was requested by users of this module) is forbidden by the registrars.
