How to Find Out Who Owns an IP Address

Every internet protocol (IP) address used on the internet is registered to an owner. The owner may be an individual or a representative of a larger organization such as an internet service provider. Many websites don't conceal their ownership, so you can look up this public information to find the owner. However, some services allow the owner to remain anonymous. As a result, their contact information and name are not easily found. ARIN WHOIS service queries the American Registry for Internet Numbers (ARIN) for an IP address and displays who owns the IP address and other information such as a contact number, a list of other IP addresses in that range with the same owner, and dates of registration. For example, for the 216.58.194.78 IP address, ARIN WHOIS says the owner is Google. Lifewire / Alex Dos Diaz
