Frequently Asked Questions About DNS, Domains & Security Certificates

DNS (Domain Name System) is a hierarchical and decentralised naming system for computers, services, or other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates domain names meaningful to humans into the numerical IP addresses needed for locating and identifying computer devices and services with the underlying network protocols. By providing a worldwide, distributed directory service, the Domain Name System has been an essential component of the functionality of the Internet since 1985.

A domain is a unique name that identifies a website on the Internet. It is made up of two parts: the top-level domain (TLD) and the second-level domain (SLD). The TLD is the suffix at the end of the domain name, such as .com, .net, or .org. The SLD is the part of the domain name that comes before the TLD, such as google.

A security certificate is a digital document that binds a cryptographic key to a website's domain name and organisation identity. When a user visits a website that uses HTTPS, their browser checks the security certificate to make sure that the website is who it claims to be and that the connection is secure.

What are the benefits of using DNS, domains, and security certificates?

  • DNS makes it easy to find websites on the internet. By translating domain names into IP addresses, DNS allows users to navigate to websites without having to memorize the numerical IP addresses of each website.
  • Domains help to establish a brand identity online. A unique domain name is a valuable asset for any business or organization. It helps to create a professional image and makes it easy for customers to find your website.
  • Security certificates protect users from phishing attacks and other malicious activity. By verifying the identity of a website, security certificates help to ensure that users are communicating with the intended website and that their data is protected.
