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:

1. A web user enters a readable domain name of a website into the address bar of their preferred browser.
2. Their device then sends a DNS request to the ISP (Internet Service Provider) of the user.
3. The ISP will determine if the domain name is associated with an IP address.
4. When the IP address is located, the domain name is sent back to the device of the user.
5. 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.
