What is DNS and How It Works

DNS (Domain Name System) is often referred to as the “phonebook of the internet.” It translates domain names into IP addresses.

How DNS Works

When you enter a website address, your device sends a request to a DNS server to resolve the domain into an IP address.

DNS Process

• DNS query is sent
• DNS server responds with IP address
• Connection is established

Types of DNS Servers

• Recursive Resolver
• Root Server
• TLD Server
• Authoritative Server

Why DNS is Important

Without DNS, users would need to remember IP addresses instead of domain names.

Conclusion

DNS plays a critical role in internet functionality and performance.
