Dns CNAME
=========

Today I have learned something new.

In the DNS world there is the concept of alias. An DNS alias is a kind of surrogate for any existing domain name that usually only forwards to an existing FQDN.
If I tell somebody we would like to setup CNAME for any FQDN, this means that I want an alias for an existing domain name.

While almost everybody understands this request correctly, syntactically it is wrong.

`CNAME` is an abbreviation for `Canonical Name`, which is basically the true name of a DNS entry. `Wikipedia <https://en.wikipedia.org/wiki/CNAME_record#Possible_confusion>`_ has a good explanation on it.

What you want to say is: Can I have an alias for the CNAME, please?
