ANAME Records

Faster, Smarter and More Accurate Than Ever

CNAME RECORD AT THE APEX

Enjoy all the functionality of a CNAME, but at the root or apex of your domain. That means you can point the root of your domain (example.com) to an FQDN, like the one you get from your CDN provider (example.cdn.com). You can also point the root to multiple FQDN's, without breaking RFC's.

But this isn’t the ANAME you’re used to... We have completely overhauled our ANAME service to meet the demands of modern cloud-based infrastructures — namely, with the advent of cloud environments that require regional IP addresses.

Our ANAME records are more Geo-Accurate than any other provider. You can use ANAME records with any of our GeoDNS services, and your queries will be answered based on the location of your end-users (not the location of our data centers).
‍
‍Unlike other providers, Constellix ANAME has no limitations and acts just as a normal CNAME would, but at the root of your domain.

‍You can use ANAME records with any of our other services, with any CDN provider that you want. ANAME also works with our multi-CDN management service and provisioning feature if you choose to use more than one CDN provider.

ANAME TECHNOLOGY
How It Works

ANAME records act like a CNAME record, but at the root of your domain. Since CNAME records don’t support this functionality, we engineered our own record type that enlists the help of a network of resolving nameservers that check what IP address (IPv4 or IPv6) your hostname resolves to.

We then update your ANAME record to point to that IP address and propagate the update to all the nameservers in our network. Every time the record is queried, we’ll check the hostname again to see if the resolution has changed. That way, every one of your users gets the most accurate and current response.

Unlike other providers, there is no lag in ANAME resolution because record updates are done at the time of the query rather than when TTL’s expire.

If our resolvers are unable to reach your hostname, our nameservers will return the cached IP address from an earlier query. This service also supports our GeoDNS functionality, which means each nameserver will cache the IP that resolved for that specific location.

EDNS + ANAME
The Most Accurate ANAME

The secret behind ANAME’s amazing accuracy is an extra piece of information that comes along with every query, called the EDNS client subnet. This information is passed along to each resolving nameserver, authoritative nameserver, and then eventually the service that the ANAME record is pointing to --usually a CDN service.

Since Constellix ANAME supports EDNS, whenever a user makes a query to an ANAME record we are able to tell where the user is located based on the EDNS client subnet. We then pass that information along to the hostname where the query will eventually resolve.

That means if you are using an ANAME record to point your domain to a CDN, all the CDN decisions will be made based on the actual locations of your end-users, rather than the location of our nameservers.
