nop,
Just from peaking in the source code:

sub TLDs {
        {
        COM => 'whois.nsiregistry.com', 
        NET => 'whois.nsiregistry.com', 
        ORG => 'whois.nsiregistry.com'
        }
}

You could try changing one of these. There is another possibility. According to the docs on CPAN, there is only a finite list of registrars that are supported. Depending on which registrar is returning the value, it may just not know how to parse it.
