What is DNS?
The Domain Name System (DNS) acts as the phonebook of the internet, translating domain names like example.com into IP addresses. When a user types a domain into a browser, DNS servers match it to the correct IP address of the web server hosting the site.
How DNS Works
DNS involves several types of servers: recursive resolvers, root name servers, TLD name servers, and authoritative name servers. DNS records include A, CNAME, MX, and TXT types, each serving different purposes.
Proper DNS configuration is essential for website uptime and email delivery.
