Domain Name System
1
a decentralized naming system used on the Internet to translate human-readable domain names into numerical IP addresses that computers can understand, enabling the proper routing of data between devices and servers
DNS, or Domain Name System, is a system that translates human-readable website names, like www.example.com, into numerical IP addresses that computers use to identify each other on the Internet. It acts as a phonebook for the internet, helping users access websites by typing in easy-to-remember names instead of complex numbers. When a user types a website address into their browser, DNS servers quickly find the corresponding IP address, allowing the user to connect to the correct website. Without DNS, people would need to remember long strings of numbers to visit websites.
- The Domain Name System (DNS) translates domain names into IP addresses, allowing users to access websites by typing in human-readable URLs.
- DNS servers play a critical role in internet infrastructure by resolving domain names to their corresponding IP addresses.
- DNS provides a hierarchical naming system that organizes domain names into manageable domains and subdomains.
- DNS lookup queries are performed to retrieve the IP address associated with a domain name, enabling internet communication.
- DNS caching improves performance by storing recent DNS lookup results locally, reducing the time required to resolve domain names.
