About A records

An A record maps a name such as www.example.com to an IPv4 address such as 93.184.215.14. It is the most common DNS record: every website, mail server and API needs one (or an AAAA record for IPv6).

A name can have several A records, and clients pick one of them, which spreads the load. If a name has a CNAME instead, the lookup follows it and shows the addresses at the end of the chain.

Frequently asked questions

Can a domain have multiple A records?

Yes. Clients choose among them, which gives simple load balancing and failover.
