When I have an account let's say ABC.COM for example is the primary domain. That account has a bunch of addon domains. Each Addon created in Cpanel by default has an ftp account created. This seems to create all kinds of dns entries in the main domain's DNS Zone. There will be A records and TXT records created for all these domains, even though these domains will have their own DNS Zone records. Are they necessary? They seem to be clutter.
