Question about Editing DNS zone files

Generally speaking, your web hosting server should be clustered directly to each of your nameservers in a write-only configuration. This means you should make zone changes on that hosting server and be able to sync it out to the cluster. While there are opinions on how this should be set up, what I described is the most efficient and secure one. This would mean, however, that you could not edit zones from servers that zone does not already exist on.
