What is DNS and How Does It Work? A Comprehensive Guide
What is DNS?
DNS (Domain Name System) is a system that converts domain names to IP addresses on the internet. For example, when you type "eastweb.ro" in your browser, the DNS system converts this domain name to the corresponding IP address and directs you to the correct web server.
Without DNS, you would have to remember long numerical IP addresses to visit websites. This system makes the internet convenient and accessible.
How Does DNS Work?
The DNS process occurs in several steps:
- Query Process: Your browser initiates a DNS query for a domain name
- Recursive Resolver: Your Internet Service Provider's (ISP) DNS server receives the query
- Root Nameserver: The server that indicates the initial address processes the query
- TLD Nameserver: The server carrying Top Level Domain (.ro, .com, etc.) information comes into play
- Authoritative Nameserver: The domain owner's server returns the IP address
This process completes in a fraction of a second and happens without your awareness.
DNS Record Types
There are various record types in the DNS system:
- A Record: Converts a domain name to an IPv4 address
- AAAA Record: Converts a domain name to an IPv6 address
- CNAME Record: Creates a domain alias
- MX Record: Specifies the email server
- TXT Record: Contains verification and security information
- NS Record: Carries nameserver information
