DNS lookup

DNS Lookup


Have you ever wondered how your computer is able to access a website by simply typing a URL into a browser? The answer lies in the process of DNS lookup.


DNS (Domain Name System) is like a phonebook that translates human-friendly domain names, such as www.google.com, into machine-readable IP addresses, like 216.58.194.174. When you type a URL into your browser, your computer sends a request to a DNS server to resolve the domain name into its corresponding IP address.


DNS lookup happens almost instantaneously, allowing your computer to connect to the correct IP address and retrieve the desired website content quickly. Without DNS lookup, accessing websites by IP address would be cumbersome and prone to errors.


There are two types of DNS lookup - recursive and iterative. Recursive lookup involves the DNS server finding the entire address by itself, while in iterative lookup, the DNS server only provides a part of the address and requests the rest from other DNS servers.


DNS lookup is an essential process that enables efficient and secure internet communication. By properly configuring your DNS settings, you can optimize your internet speed and ensure a reliable connection.
