Frequently Asked Questions

What is a DNS record?

DNS records are instructions in the Domain Name System that tell browsers and servers how to handle a domain. A records map the domain to an IP address, MX records specify mail servers, NS records list name servers, and TXT records store text-based verification data.

What is an MX record?

MX (Mail Exchanger) records specify which mail servers handle email for a domain. If you're setting up email or checking why email delivery is failing, verifying MX records is the first step.

What is a TXT record used for?

TXT records contain text data for a domain. They are commonly used for domain verification (Google, Meta), SPF records (email anti-spoofing), DKIM keys (email authentication), and DMARC policies.
