Thanks for the suggestion, but neither Net::Whois or Net::ParseWhois can retrieve records by ip address which is what I need to do. I failed to mention that this script is part of a larger script that parses firewall log files for dropped traffic, creates an abuse email from a template, obtains the email address (from the above code), includes a snipet of log file for evidence, and sends it on its merrily way. It has been working really well except for this little issue. I would post the entire script, but it is 300 lines long and I've learned if you post too much code to perlmonks, most monks won't reply.
