WHOIS, the system used for querying databases of information on domain name registrations and IP addresses, has been a vital tool for journalists, security researchers and law enforcement in identifying and tracking spammers, phishers, identity thieves and other cybercriminals.

How will this impact cybersecurity? Does WHOIS raise legitimate privacy concerns? Shane Tews, President of Logan Circle Strategies, visiting fellow at the American Enterprise Institute, and Tim Chen, CEO of DomainTools, join the show to discuss.
