A record
Maps a name to IP addresses.
CNAME record
Maps a name to another name. It should only be used when there are no other records on that name.
ALIAS record
Maps a name to another name, but can coexist with other records on that name.
URL record
Redirects the name to the target name using the HTTP 301 status code.
- The A, CNAME, and ALIAS records cause a name to resolve to an IP. Conversely, the URL record redirects the name to a destination. The URL record is a simple and effective way to apply a redirect for one name to another name, for example redirecting www.example.com to example.com.
- The A name must resolve to an IP. The CNAME and ALIAS records must point to a name.
- Never use a CNAME record for your root domain name (e.g. example.com).
