A domain is a unique identifier used to locate a website on the internet. It is essentially the address that people type into their web browser to access a particular website. Domains consist of two main parts – the top-level domain (TLD) and the second-level domain (SLD). The TLD is the last part of the domain name, such as .com, .org, .net, .edu, .gov, etc. There are currently hundreds of TLDs available, and each one is intended for a specific purpose. For example, .com is typically used for commercial websites, while .edu is reserved for educational institutions.


The SLD is the part of the domain name that comes before the TLD. It is often the name of the website or business that the domain represents. For example, in the domain name “example.com,” “example” is the SLD.

Domain names are registered with domain name registrars, which are companies authorized by the Internet Corporation for Assigned Names and Numbers (ICANN) to manage the registration of domain names. Once a domain is registered, the owner has the exclusive right to use that domain for a specified period of time (usually one year), after which it must be renewed. Domains can have a significant impact on a website’s visibility and success. A good domain name should be memorable, easy to spell, and relevant to the content or purpose of the website. It can also affect a website’s search engine optimization (SEO) and online branding efforts. Overall, domains are an essential part of the internet infrastructure and play a crucial role in how we access and interact with online content.


To find out who owns a domain, you can use a WHOIS lookup service. WHOIS is a protocol that allows you to query a database of domain name registration information. There are several online tools and services that provide WHOIS lookup functionality, including:


  • ICANN WHOIS: The Internet Corporation for Assigned Names and Numbers (ICANN) maintains a publicly accessible WHOIS database that contains information on registered domain names. You can use the ICANN WHOIS lookup tool at https://whois.icann.org/ to search for domain name registration information.


  • Domain registrar WHOIS lookup: The registrar that the domain is registered with will also have a WHOIS lookup tool available on their website. Simply visit the website of the domain registrar and look for a WHOIS lookup tool.


  • Third-party WHOIS lookup services: There are many third-party WHOIS lookup services available online. Some popular ones include WHOIS Lookup at https://www.whois.com/whois/ and DomainTools at https://whois.domaintools.com/. These services often provide additional information beyond what is available in the ICANN WHOIS database.


Keep in mind that some domain owners may choose to keep their contact information private or use a domain privacy service to obscure their personal details. In these cases, the WHOIS lookup may only reveal the contact information of the privacy service or domain registrar.
