DNS Record FAQs

What is an A record?

An A record maps a domain name to an IPv4 address. It's the most basic DNS record — when someone types your domain in a browser, the A record tells the browser which server IP to connect to.

What is an MX record?

MX (Mail Exchange) records specify which mail servers handle email for a domain. If you send an email to someone@example.com, the MX record tells the sending server where to deliver it.

What is a TXT record?

TXT records store arbitrary text data in DNS. They're commonly used for email authentication (SPF, DKIM, DMARC), domain verification for Google/Microsoft services, and other ownership proofs.
