Perfect whois server to run your whois server for your registrar. Will need some configuration to be ICANN compliant under the 2013 Registrar Accreditation Agreement, but it's worth it :) Great software, thank you Klaus. All the best from your friends at DomainCocoon.
A server for your Whois server needs. The newly introduced feature of customizing the output response in 0.3.1.0 release is great.
