A zone is a group of related DNS records all under the same administrativ= e control. 'Related' meaning they all end in the same sequence of labels. = Zone boundaries are determined pretty much by delegation to another set of DNS= servers. So there's a '.org' zone containing primarily the NS records for all the = domains registered under .org. This is distinct from the 'thought.org' zone you control and here all the sub-entries like www.thought.org or plato.thought.org are part of the same zone. It's not an entirely cut an= d dried definition, but you can think of a zone as 'the chunk of the DNS sp= ace that one person controls.' > thought.org is my one domain, altho i've got several virtual=20 > websites. =20 'domain' in DNS-speak is any sequence of labels[*] known to the DNS. So even if the DNS data is a host name, an e-mail address, the name of a whole network, a crypto key for DKIM or DNSSEC or some aggregate service = name hosted across several different servers via SRV records, they're all doma= ins. Domains can be absolute (ie. from the root of the DNS) or relative to som= e intermediate domain. ie. 'thought.org' is your only zone, although you've got several domains within it for virtual websites. Cheers, Matthew [*] And a 'label' is a sequence of characters not including the separator= character '.' -- a domain is hence a sequence of labels joined together by '.' characters.
