How it works
Understanding DNS Records
The Domain Name System (DNS) is the internet's phone book. It translates human-readable domain names like example.com into the IP addresses that computers use to communicate. Without DNS, you would need to remember numerical addresses for every website you visit.
DNS records are stored on authoritative nameservers and are queried every time a browser, email client, or application needs to find a server. Different record types serve different purposes — from routing web traffic (A/AAAA records) to directing email (MX records) and verifying domain ownership (TXT records).
A
Maps a domain to an IPv4 address
AAAA
Maps a domain to an IPv6 address
CNAME
Creates an alias pointing to another domain
MX
Directs email to the correct mail server
NS
Specifies authoritative nameservers for the domain
TXT
Stores text data for verification and policies (SPF, DKIM)
