WHOIS IP Lookup

IP WHOIS Lookup - Find Owner of IP Address

Our IP owner lookup tool is a free online utility that helps you check who owns an IP address. It checks a public IP address (IPv4 or IPv6) against available WHOIS and RDAP registration data.

It performs a WHOIS lookup to find the registered organization, IP range, and ASN associated with the IP address. It also provides available registration and network details, such as the WHOIS server, network handle, registration date, and last changed date.

What is WHOIS IP Address Lookup?

WHOIS IP Lookup is the process of retrieving registration and network details associated with a public IP address. This lookup is the fastest way to identify the organization or network associated with an IP.

Many people perform WHOIS IP address lookup to check registration, organization, and abuse contact details linked to an IP address. Our IP address owner lookup tool offers a free way to find owner of IP. It supports two data sources:

• WHOIS: Checks traditional WHOIS registration data.
• RDAP: Checks registration data through the newer Registration Data Access Protocol. 

How to Check WHOIS IP Information?

Follow these steps to check WHOIS IP data using our IP owner lookup tool.

• Enter a public IPv4 or IPv6 address in the input field.
• Choose an IP data source between WHOIS and RDAP (latest) and click the ‘Check Now’ button.
• View the IP address owner, registration, network, and other available IP details.

What Information Does IP WHOIS Lookup Show?

The Whois IP lookup tool organizes the details into several sections. This makes it easier to understand both the basic and detailed IP information.

Whois IP Location

At the top, our tool shows you the IP Location data. This includes city, state, and country name linked to the IP registration record. 

Owner or Organization

Our tool also shows the organization listed in the IP registration data. This may identify the network operator, ISP, hosting provider, or organization associated with the address range. 

Provide ASN

The tool shows the Autonomous System Number (ASN) linked to the provided IP network.

Resolve Host

When you check WHOIS IP information, our tool shows the hostname if it is linked to that IP. You can also find the hostname through reverse DNS lookup.

IP Address Range

An IP address usually belongs to a larger network range. In the results, you will see the start and end addresses in that range provided by the registry in CIDR format.

Network Name and Handle

Depending on the available data, a WHOIS record lookup shows the network name and a unique network handle. These values help identify the registered network in the registry database.

WHOIS Server

The WHOIS server identifies the registry service that returned the WHOIS information. The server can vary based on the IP address and the registry that manages its address space.

Registration and Last Changed Dates

The lookup results also tell when the network record was registered and when someone last changed it. These dates describe the registry record. They do not show when a person started or stopped using the IP address.

Why Check an IP WHOIS Record?

People check IP WHOIS records for many reasons.

• Identify an IP organization: Find the organization listed for an IP or network.
• Check an IP range: See which address range contains an IP.
• Find an ASN: Check the autonomous system linked to a network.
• Research an Unfamiliar IP: Learn more about a public IP address.
• Check Network Information: Review network names, handles, and other registry data.
• Find Reverse DNS information: See whether the IP has a registered hostname.
• Review Contact Details: Find public abuse or technical contacts when the registry provides them.
• Investigate Network Activity: Use registration data as one source of information during network research.

IP WHOIS Lookup vs IP Geolocation

IP WHOIS and IP geolocation can both provide information associated with an IP address, but both serve different purposes.

• IP WHOIS lookup focuses on registration and network information. It can show the organization, IP range, ASN, and registry details linked to an IP.
• IP geolocation estimates a geographic area associated with an IP address. It shows a country, region, city, or other location data.

Neither method should be treated as a way to find someone’s exact physical location.

What an IP Owner Lookup Cannot Tell You

An IP WHOIS lookup provides public registration information. It does not provide private information about the person whose using an IP. For example, a WHOIS result cannot tell you:

• Exact location of a device
• Home address of an IP user
• Name of the person using an IP
• Private account information
• Real-time location of a person
• Private activity linked to the IP

Frequently Asked Questions

Who Owns This IP Address?

To know who owns the IP, use our IP WHOIS lookup. It performs a lookup and shows the organization or network provider associated with the IP address. It generally cannot identify the individual person using the IP address.

Can I Perform an IPv6 WHOIS Lookup?

Yes. Our IP WHOIS tool can retrieve IP address owner information for a public IPv6, including the linked organization, address range, ASN, and registry details.

Can I Find the Owner of an IP Address?

No. You can use an IP owner lookup to check the organization or network listed in public registration data. However, this information does not identify the individual person using the IP address. Generally, WHOIS and RDAP provide registration and network information, not private subscriber or account details.

Can WHOIS Find the Exact Location of an IP?

No. WHOIS data provides registration-related information. The WHOIS IP location can be inferred based on the owner’s registered IP details. Neither should be treated as an exact physical location for the person or device using the IP.
