The specific steps to create a CNAME record may vary depending on the DNS provider you are using, but generally, you will need to do the following:

Log in to your DNS management interface

Locate the zone file for the domain you want to create the CNAME record for

Add a new record to the zone file and select "CNAME" as the record type

In the "Name" or "Host" field, enter the subdomain you want to create the CNAME record for (e.g. "akky.example.com")

In the "Value" or "Points to" field, enter the destination hostname or URL that the subdomain should resolve to (e.g. "akky.mx")

Save the record

Wait for the DNS to propagate (it can take a while)

You may need to consult your DNS provider's documentation for specific instructions on creating a CNAME record
