Get the Inside Scoop About IP WHOIS!

Here’s every key detail you’d need to know about IP WHOIS.

What is a WHOIS database?

The WHOIS database is a publicly accessible repository containing information about IP addressesdomain namesand registered owners. It provides details such as the organization or individual associated with the IP addresscontact informationregistration datesand administrative details.

What is IP Address ownership?

IP address ownership refers to the legal and administrative control over an internet protocol address. It signifies that a particular individualorganizationor entity has the rights and responsibilities associated with using and managing a specific IP address or range of IP addresses. It is typically determined by the allocation and registration process by the Internet Assigned Numbers Authority (IANA) and the regional Internet registries (RIRs) they oversee.

How are IP addresses allocated and managed?

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 informationfor exampleIP addressroot zone management in DNSASNs allocationand 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 customersincluding ISPs and end-user organizations. Every IP address that floats on the global public internet is administrated by one of the five RIRseach 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 StatesCanadaand many Caribbean and North Atlantic islands.
• Asia-Pacific Network Information Centre (APNIC) Manages IP addresses for AsiaAustraliaand 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 Europethe Middle Eastand the former USSR.

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.

Is IP WHOIS the same as WHOIS Domain?

No. IP WHOIS and WHOIS Domain lookup are not the same. IP WHOIS is used to obtain information about an IP address's ownership and registration details. In contrastdomain WHOIS provides information about a domain name's ownership and registration details. While both processes involve querying a WHOIS databasethey retrieve information about different Internet resources.

What are the objectives (purposes) of an IP WHOIS lookup?

IP WHOIS Lookup helps you fulfill multiple objectives that include:

• • Identifying the owner of an IP address 
  • Identifying the country/region associated with IP
  • Investigating network suspicious activities
  • Helping network administrators troubleshoot network issues.

Can I perform an IP WHOIS lookup for both IPv4 and IPv6 addresses?

Yesour IP WHOIS lookup supports both IPv4 and IPv6 addresses. Using our IP WHOIS lookup toolyou can obtain WHOIS information for both IP addresses. 

Does IP WHOIS lookup provide information about an IP address from the private network?

The IP WHOIS lookup tool and WHOIS databases do not provide any information about the IP addresses that belong to private (secured by proxy servers or VPNs) networks.

Can I see the WHOIS details of the end user?

The WHOIS IP address results provide the organization or individual's name against which the IP is registered in the IP WHOIS Database. Typicallythe owner is none other than the internet service provider (ISP). It’s possible to get the end-user information only if the ISP allows itwhich usually doesn’t happen.

Is IP WHOIS lookup legal?

Yes. Performing an IP WHOIS lookup is legal. This is because the information obtained through it is publicly availableand anyone can access it. Howeverit's essential to respect privacy regulations and use the obtained information responsibly and within the boundaries of the law.
