Go for Lookup IP WHOIS information using the IP WHOIS Lookup tool for any allocated IP address.
The IP WHOIS information contains
Someone somewhere owns an IP address that is in use on the internet. An Internet Assigned Numbers Authority (IANA) is responsible worldwide for managing the allocation of IP addresses. The organization is responsible for reporting the information, for example, IP address, root zone management in DNS, ASNs allocation, and other Internet numbers and Internet Protocol-related symbols.
The Internet Assigned Numbers Authority further assigns Internet number resources (IP addresses and AS numbers) to regional internet registries (RIRs). These registries are responsible for allocating and registering Internet number resources within a specific region of the globe.
Each RIR has its regional rules and policies and follows those to assign the IP addresses and AS numbers to their customers, including ISPs and end-user organizations.
Every IP address that floats on the global public internet is administrated by one of the five RIRs, each working within a specific region of the globe. The RIRs and their regulatory areas are as follows.
Note: Suppose an RIR assigns a block of IP addresses to one of its ISP in the United States. The same ISP further assigns a sub-block of those IP addresses to one of their customer in Canada. The IP address's location still is reported as being in United States.
However, for more accurate geolocation data and to get IP's location from several geolocation databases, you may use the IP geolocation tool.
To find the WHOIS information of a particular IP address. Perform the following steps.
You will get the information you should contact to reach out to the IP address owner from the IP WHOIS results. You will most likely get the Internet Service Provider (ISP) information to whom the IP address is assigned. If someone tries to spam or hack you, etc., it's best to dig out the abuse information included in the results. Otherwise, using the non-abuse contact information will be your best option when attempting to reach the controlling party.
The WHOIS results provide the organization or individual's name against which the IP is registered in the IP WHOIS Database. Frequently it's an internet service provider (ISP). However, it's impossible to get the end-user information to whom the ISP assigns the IP. Only ISP has the original and exact details of its end-user. You can get it if the court directs the ISP to provide the end-user name, address, and contact information.
