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).

C. Record Mode: The Record Mode is how you enable settings like Failover, Record Pools, or Round Robin with Failover. You can read more about these settings here.
D. Geo Proximity: You can select a Geo Proximity rule to apply to the record, for more information on Geo Proximity, click here.
E. IP Filter: You can select an IP Filter to apply to the record, for more information on IP Filters, click here.
F. Disable Record: Information on the NX Domain feature can be found in the Disabling a Record tutorial.
G. FQDN/Host: the fully qualified domain name you want to point to.
H. Notes: Add a helpful note with keywords so you can search for your records later.
