DNS stands for Domain Name System and works like the internet’s address book by directing names to the right services.
Key Points
- A records point domains to IP addresses, MX records route email and CNAME records create aliases.
- TXT records are commonly used for verification, SPF, DKIM and DMARC email policies.
- Without DNS, users would need to remember server IP addresses instead of simple domain names.
- DNS changes do not always appear instantly because records are cached around the internet.
- Clean DNS management is one of the most important parts of getting a domain, website and email setup right.
Frequently Asked Questions

Can one bad DNS record break email?

Where do I manage DNS?
You usually manage DNS where your nameservers are hosted.
