	Nameservers can NEVER be CNAMES.  It breaks fetching of glue.

	Since you are changing the name of the nameserver you need
	to add a host record (glue) for the new name then you need to
	change all the delegations to refer to the new name.

	If you were just changing the address then all you would
	need to change is the host record (glue).
