A domain name is a unique identifier used to access websites on the internet, serving as an easily memorable form of an IP address. Each domain name is unique and is typically associated with the name of a website. The process of domain name registration involves officially recording these unique names, which is done through a registration company chosen by the user.

Whois information for a domain name consists of a dataset created during the registration of the domain, containing details like the name, phone, email, and physical address of the domain owner. This information identifies who registered the domain and how to contact them. While domain owner details are generally public through whois queries, there are instances where this information can be hidden using a service known as "private whois registration" or "whois protection". This service protects the identity of the domain owner while providing a proxy address for contact purposes.

Domain name registration and whois query services are commonly provided by web hosting and domain registration companies. These services are fundamental for the existence and management of websites on the internet.

For example, EKASUNUCU Domain Registration and EKASUNUCU Whois Query pages offer services for domain name registration and whois queries. These sites assist users in selecting, registering, and querying information about domain names. They also offer various services related to the management and security of domain names.
