Frequently Asked Questions

What is an A record?
An A record maps a domain name to an IPv4 address. When you visit a website, your browser looks up the A record for the domain to find the server's IP address.
What is an MX record?
MX (Mail Exchange) records specify which mail servers accept email for a domain. The priority number determines which server is tried first — lower numbers mean higher priority.
What is a TXT record used for?
TXT records store text data for verification and authentication purposes. Common uses include SPF records (email spam prevention), DKIM keys, DMARC policies and domain ownership verification for Google, AWS, etc.
