This test will query the American Registry for Internet Numbers (ARIN) database and tell you who an IP address is registered to. Generally speaking, you will input an IP address and find out what ISP or hosting provider uses that block for its customers. Very large end customers may have there own ARIN allocations.

A public address that is visible on the Internet. Contrast with an "unregistered IP" address, which is private and not exposed to anyone outside of the company or home network. ARIN is a nonprofit, member-based organization that administers IP addresses & ASNs in support of the operation and growth of the Internet. Registered hosts or "glue records" are a way of making the IP address of the name server known when it is a subdomain of the domain for which it serves. For example, If your domain is example.com and your name servers are ns1.example.com, ns2.example.com, ns3.example.com, and ns4.example.com, you would create four registered host records The IP Address Ownership tells the name of the original organization or individual whose name the IP is registered in the IP Whois Database, and does not tell the Whois details of the real user to whom the Internet Service Provider assigns the IP. An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.. Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. The "IP" of "IP address" stands for "internet protocol." If you haven't checked out our IPv4 vs IPv6 guide, now is a good time to do so because it provides context here. An IP address lookup will determine the geolocation of any IP address. The results of the IP address lookup will show you the city, state/region, postal/zip code, country name, ISP, and time zone. This data can be used by various agencies to find the exact owner of any IPv4 or IPv6 address.

Under Listen on, click to select the Only the following IP addresses check box. Type the IP addresses that you want the server to listen on. Include only the IP addresses of the interfaces for which you want a host A record registered in DNS. Click OK, and then quit the DNS Management MMC.

IP WHOIS Lookup. Lookup IP WHOIS information using the IP WHOIS Lookup tool for any allocated IP address. This tool will provide you with the IP Address owners contact information. The results will also show the Regional Internet Registry (RIR) who assigns the IP, the assigned owner, location, contact information, and abuse reporting details.

An IP is a unique address of a server on the internet. Similar to how a telephone number allows you to connect to a specific phone on the telecom network, similarly, an IP address allows your computer to connect to a specific server on the internet. Domain names and IP numbers are the framework upon which the entire world wide web is built.

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.
