How to Look up an IP Address Owner – Lifewire
What to Know
If you know the IP address, enter it on ARIN WHOIS to view ownership.
To find an IP address, open Windows command prompt (Start + CMD on Windows) > type ping
To find an IP address owner if you don’t know the IP address, use UltraTools,, GoDaddy, or DomainTools.
This article explains how to find the owner of an IP address, whether you know the IP address or not. Also included are instructions for finding an IP address using the Windows command prompt.
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 that the owner is Google and its IP range falls between 216. 192. 0 and 216. 223. 255.

If You Don’t Know the IP Address
Some services are similar to ARIN WHOIS, but they can search for the website owner even when the website’s IP address is unknown. Examples include UltraTools,, GoDaddy, and DomainTools.
To use ARIN WHOIS to find the owner of an IP address, convert the website to its IP address using a ping command in the Windows command prompt. With the command prompt open, type the following to find the website’s IP address:
Replace websitename with the website you want to find the IP address for.
About Private and Other Reserved IP Addresses
Some IP address ranges are reserved for use on private networks or for internet research. Attempting to look up these IP addresses in Whois returns an owner such as Internet Assigned Numbers Authority (IANA). However, these same addresses are employed on many home and business networks worldwide. To find who owns a private IP address in an organization, contact their network system administrator.

About IP WHOIS – Check Who Owns an IP Address
IP WHOIS Lookup Tool offers a free IP Lookup Service to check who owns an IP address. Just enter an IP and perform the IP Lookup to find which organization or individual owns that specific IP address.
IP WHOIS Lookup Tool
Go for Lookup IP WHOIS information using the IP WHOIS Lookup tool for any allocated IP address.
The IP WHOIS information contains
The contact information of the IP address owner.
The Regional Internet Registry (RIR); which 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 owner of the IP you are researching.
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 Africa 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 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.
How to find the WHOIS information of the given IP address by using the IP WHOIS Lookup tool?
To find the WHOIS information of a particular IP address. Perform the following steps.
Open the IP WHOIS Lookup tool.
Enter a valid IPv4 or IPv6 in the “Enter any Valid IP Address” section.
After entering the IP address, click on the “Lookup IP” button.
The tool performs the IP WHOIS lookup and provides you the WHOIS info of that particular IP address.
IP WHOIS Results
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.
Can I see the WHOIS details of the end-user?
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.
IP Address Lookup – Lookup IP Location details – What Is My IP?
IP Address Lookup
An IP address lookup determines the location of any IP address. The results provide quite a bit of information, including information the city, state/region, postal/zip code, country name, ISP, and time zone. Consequently, this data is used by various agencies to find the owner of an IPv4 or IPv6 address.
IP Address Location Accuracy
It’s important to understand that no IP Lookup tool is 100% accurate. IP lookup results are shown from several different IP location databases, and each database reports differently.
There are many other factors as to why results are not 100% accurate. Factors include:
Where the IP address was registered
Where the controlling agency is located
Whether the user has a proxy or VPN
Whether the connection is cellular or not
For example, if you are in the US and the controlling agency of the IP is located in Canada, the lookup data may show Canada as the IP location. It is not uncommon to see a Canadian IP while searching an IP address in the northern US.

IP Address Results
When using an IP address lookup tool, users often think they are going to find the exact location of an IP address. This is simply not true. No IP address database can provide the exact physical address of an IP address location. At best, you’ll get the exact city in which the user of the IP is located.
Only the Internet Service Provider (ISP) can provide an exact physical address of an IP. ISPs usually have logs of which user was assigned an IP at any given time. There are usually limits as to how long an ISP stores these records. However, without a police warrant, or some sort of legal document, the ISP is unlikely to turn over any information.
If you receive an offensive or fraudulent email, don’t expect an ISP to give you the mailing address of the user of that IP address. Instead, turn over the communications to the authorities and let them do their job.
Update Your IP Location
If you find that your IP location information is incorrect, you can always reach out to any of our IP address data providers and update your IP address location.
In conclusion, if someone has sent a harassing or potentially fraudulent communication, the best you can do is to file a complaint with the authorities or the ISP. Then, forward all the relevant information from the questionable communication.
