What is an ALIAS Record?

ALIAS record is a type of DNS record build in the ClouDNS and works in a similar way as the CNAME record. The ALIAS record will allow you to add multiple hostnames for the same subdomain and can be used for the root domain too. This new build in our system type of DNS record gives you a chance to make a Round-Robin DNS between multiple CNAME and A records. All added ALIAS records are updated by our system in a short period of time and when you make a DNS request at the hostname with such record, you will receive an answer with pure A or/and AAAA records. This type of DNS record can be added and managed from our control panel or via the HTTP API.

The ALIAS record has the following look in your ClouDNS Control Panel:

Why do you need an ALIAS record?

The most significant benefit of the ALIAS record is that you can add it to the root domain. As you’ll recall, CNAME records can’t be added for the root domain. And here is where the ALIAS comes in. It is an analog of the CNAME record so to say. It works in a similar way, but you can use it for the root domain as well.

Another con of the CNAME is its impossibility to coexist with any other data for the same host. But there isn’t such an obstacle for the ALIAS. You can combine the ALIAS records with all the types of DNS records except CNAME and Web Redirect. For that reason, you could use the ALIAS record to achieve a Round-Robin setup without a problem.
