ALIAS record is one of the not-so-popular DNS records, but it is also very interesting. So let’s explain a little bit more about it.
ALIAS record explained.
The ALIAS record is a DNS record, which helps with linking two hostnames. Simply it is explaining that one of the hostnames is just another way to write the other one. This DNS record is not one of the standard ones, and actually, not every Managed DNS provider is offering it. The main benefit that comes with applying this record is that it can coexist with other DNS records, such as MX record. For example, the CNAME record is not able to do the same. Another amazing thing about it is that it will take a lot less time and present the other hostname and IP address.
