Use !whois-dns to lookup whois registration data for a DNS domain name.
Whois registration data for the Domain Name System (DNS) are maintained by Domain Name Registrars and Domain Name Registries and contain registrant contact information along with technical details for each domain name registration.
For the most part, the Domain Name System (DNS) maps DNS names to Internet Protocol (IP) numbers.
Usually, you do not need to prefix you query with !whois-dns and !whois should work just fine.
