What are ANAME Records
ANAME records allow you to point the root of your domain to a hostname or FQDN (Fully Qualified Domain Name). They’re basically a CNAME record but at the root level.
Before ANAME records were developed by DNS Made Easy, it was bad practice to use a CNAME record at the root. However, ANAME records operate differently from CNAME records. They are actually a combination of CNAME and A records.
Every hostname or FQDN will eventually resolve to an IP address. Constellix caches the IP address(es) that the hostname resolves to and creates A record(s) with it. Those IP(s) are expected to change, so Constellix will continue to monitor where that hostname resolves to. When it changes, Constellix will automatically update the value of the A record(s) to match the new IP(s).
