Top 10 Who is Search, Domain Name, IP Tools Sites on Sentilay

Hi Pals, This article is about a method for checking information about ownership of a domain name.

Our set of lookup tools allow you to research domain names, IP addresses, Autonomous System Number (ASN) and IP net block ranges (CIDR).


Check Whois-service is a service that allows to retreive information about the location of IP addresses, servers or websites. You can find out the owner of Internet resource and its contact details. Type in the desired domain, IP address or hostname and click “Check”.


The term ‘WHOIS’ means just what it is and asks the question: “who is?”.
Applied to the world of domain names, a WHOIS is a directory that lists a domain name’s legal and technical information.
With this information, we can determine the owner of the domain name, its contact person in the event of a problem (domain name administrative contact), as well as the technical contact administering the domain name.
The fields displayed when viewing the WHOIS are specific domain name registries, but contain the following elements:

  • the domain name consulted;
  • the names, address, telephone number, fax (if applicable), email of the domain name owner;
  • the NIC IDs of the owner, technical contact, and billing contact;
  • the addresses (or IPs) of the DNS servers;
  • The creation, modification and expiry dates the domain name consulted in the WHOIS

When consulting the WHOIS for a particular domain name, if the WHOIS returns nothing, it is because the domain name is available for registration.


The IPWHOIS Lookup tool displays as much information as possible for a given IP address, sourced from the Regional Internet Registry (RIR) to which the address belongs.

A RIR is an organization that manages the allocation and registration of Internet number resources within a particular region of the world. Internet number resources include IP addresses and autonomous system (AS) numbers.The Internet Assigned Numbers Authority (IANA) delegates Internet resources to the RIRs who, in turn, follow their regional policies to delegate resources to their customers, which include Internet service providers and end-user organizations.

Each IP address on the global public Internet is administered by one of the 5 RIRs within a particular region of the world. As such, each globally routable IP address is associated with its RIR’s region, and the RIR’s allocation policy results in an IP address being associated again with a specific country or region with a country. This association is a function of the assignees location. For example, if an RIR allocates a block of IP addresses to a large ISP in the United States, but the ISP assigns one of those addresses to a customer in Vancouver, Canada the location of the IP address will be reported as being in United States. More accurate Geo-location data may be available using the GeoIP tool.

6. WHOISHOSTINGTHIS helps millions of people make informed decisions about web hosting. There is an enormous number of web hosts, each with different options. Our primary purpose is to help people make the right choice for themselves — in the easiest way possible.


We are responsible for coordinating some of the key elements that keep the Internet running smoothly. Whilst the Internet is renowned for being a worldwide network free from central coordination, there is a technical need for some key parts of the Internet to be globally coordinated, and this coordination role is undertaken by us.

Specifically, we allocate and maintain unique codes and numbering systems that are used in the technical standards (“protocols”) that drive the Internet.

Our various activities can be broadly grouped in to three categories:

  • Domain Names
    Management of the DNS Root, the .int and .arpa domains, and an IDN practices resource.
  • Number Resources
    Co-ordination of the global pool of IP and AS numbers, primarily providing them to Regional Internet Registries (RIRs).
  • Protocol Assignments
    Internet protocols’ numbering systems are managed in conjunction with standards bodies.

We are one of the Internet’s oldest institutions, with the IANA functions dating back to the 1970s. Today the services are provided by Public Technical Identifiers, a purpose-built organization for providing the IANA functions to the community. PTI is an affiliate of ICANN, an internationally-organised non-profit organisation set up by the Internet community to coordinate our areas of responsibilities.


As per ICANN regulations, when a domain is registered, registrants must provide registrars with up-to-date contact information. This information is displayed publicly in the Whois database, which acts like a giant address book that anyone can view.

Try our Whois domain tool now to find out if that domain you’ve had your eye on has already been taken. If it’s available, great! Register it today. If it’s already in use, why not make them an offer they can’t refuse?


A Whois domain lookup allows you to trace the ownership and tenure of a domain name. Similar to how all houses are registered with a governing authority, all domain name registries maintain a record of information about every domain name purchased through them, along with who owns it, and the date till which it has been purchased.


GoDaddy WHOIS search is designed to help you by diving into the WHOIS database for information on domain registration and availability. It’ll also provide you the owner, administrator and contact information, as well as other important information.A domain name can be legally owned or held by any person, entity or organization, also known as domain registrant.
