• The Regional Internet Registry (RIR); assigns that IP address.
• The autonomous system (AS) numbers.
• The designated owner, location, contact information, and abuse reporting details.
• The number of IP addresses in the block or blocks assigned to the IP owner you are researching.

IP WHOIS Results

You will get the IP address owner's contact information 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, it's best to dig out the abusive information in the results. Otherwise, using the non-abuse contact information will be your best option to reach the controlling party.

Can I see the WHOIS details of the end user?

The WHOIS IP 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-users name, address, and contact information.

What is IP address ownership?

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.

• African Network Information Centre (AfriNIC) Manages IP addresses for the African continent.
• American Registry for Internet Numbers (ARIN) Manages IP addresses for the United States, Canada, and many Caribbean and North Atlantic islands.
• Asia-Pacific Network Information Centre (APNIC) Manages IP addresses for Asia, Australia, and surrounding Countries.
• Latin America and Caribbean Network Information Centre (LACNIC) Manages IP addresses for Latin America and the Caribbean.
• Réseaux IP Européens Network Coordination Centre (RIPE NCC) Manages IP addresses for Europe, the Middle East, and the former USSR.

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 the United States.

However, for more accurate geolocation data and to get IP's location from several geolocation databases, you may use the IP Locator.
