What is WHOIS?
WHOIS is a protocol used to query databases that store the registered users or assignees of Internet resources such as IP addresses, domain names, and autonomous system numbers.
WHOIS records typically contain the name and contact information of the organization that owns the IP address block, the network range assigned, registration and update dates, and abuse contact information for reporting network abuse.
Regional Internet Registries (RIRs) such as ARIN, RIPE NCC, APNIC, AFRINIC, and LACNIC maintain WHOIS databases for IP addresses in their respective regions.
