What is Domain Name System (DNS)?
Domain Name System, or DNS for short, is the protocol that translates readable URLs - dns-lookup.com - into numeric addresses that can be understood by computers. This is how DNS works:
- A web user enters a readable domain name of a website into the address bar of their preferred browser.
- Their device then sends a DNS request to the ISP (Internet Service Provider) of the user.
- The ISP will determine if the domain name is associated with an IP address.
- When the IP address is located, the domain name is sent back to the device of the user.
- The device can now communicate with the server of the entered domain, and the user can now view the website.
What are the Most Common Types of DNS Records?
- A (Address) - Used to point a domain name to the associated IP address.
- CNAME (Canonical Name) - Used for creating aliases of domain names.
- MX (Mail Exchanger) - Used to deliver email to a specified address.
- NS (Name Server) - Used to specify an authoritative name server for a given host.
- SOA (Start of Authority) - Used to determine key information about a DNS zone.
- TXT - Used to verify domain ownership and hold SPF (Sender Policy Framework) data.
