What is DNS?
The Domain Name System (DNS) is a system that matches domain names to IP addresses. It operates behind the scenes but is fundamental to how we access the web. When a user types in a web address, the DNS resolves that address to an IP address, enabling the user's device to find and connect to the server that hosts the website.
DNS consists of various components, including DNS servers and records. Its hierarchical structure allows for efficient resolution of queries, providing a decentralized yet unified way to handle network addresses. Each level of the DNS hierarchy plays a part in this translation process, making it a crucial point of understanding.
How DNS Works
When a user enters a website URL, the request goes through multiple steps. First, it checks the local cache to see if the address is already stored. If not, the query travels to a DNS resolver, which usually belongs to the user's Internet Service Provider (ISP). This resolver then queries the root DNS servers to find out where the top-level domain (TLD) servers are, such as .com or .org. After locating the TLD server, it contacts the authoritative DNS server associated with that domain.
Finally, the authoritative DNS server sends back the correct IP address to the resolver, which caches it for future requests. This sequence may sound tedious, but it occurs in mere milliseconds. Understanding this process helps to appreciate how essential DNS is to our online experiences and the importance of its speed and security.
Types of DNS Records
DNS records come in various types, each serving a unique purpose. Here are some of the most common record types:
