To further expand on this: you are adding a CNAME (Canonical Name) to the
dns records. Think of this as an alias. A machine can have several
CNAMEs. (like www. ftp. ns. or whatever) But CNAMES are not legal host
names for email addresses. (Though some idiot has probably done this)
Your domain space (zone) is troywolf.com. Everything to the left of
'troywolf.com' refers to host (machine) names. These are handled by
entries in your dns zone file.
So as Jeff said, it's not a matter of registering ftp.troywolf.com, it's
just a matter of changing the records in your zone file to point
ftp.troywolf.com to troywolf.com.
