Who Provides DNS Service?
In the vast realm of the internet, DNS (Domain Name System) plays a crucial role in translating human-readable domain names into machine-readable IP addresses. This translation is essential for users to access websites and online services seamlessly. But who provides DNS service? Let’s delve into the answer to this question.

Internet Service Providers (ISPs) are the primary providers of DNS service. When you connect to the internet, your ISP assigns you an IP address and provides DNS services to help you navigate the web. These DNS services are often integrated into the ISP’s overall internet connectivity package.
Moreover, cloud service providers such as Amazon Web Services (AWS), Google Cloud, and Microsoft Azure also offer DNS services. These cloud-based DNS services are designed to cater to the needs of businesses and organizations that require scalable and reliable DNS solutions.

1. Google Public DNS: Known for its speed and reliability, Google Public DNS is a popular choice among users worldwide.
