A little more detail is needed to answer your question (although if you're talking strictly DNS terms Chris' answer was quite detailed). In the context of a DNS-centred newsgroup/mailing list Chris' answer was excellent. Whether the original author was asking about the DNS is, of course, slightly open to question. Unfortunately, as you imply, computing, and network related fields in particular, are full of multivalued terms. They have to be disambiguated by referring to their particular, errm, domain.

zone vs domain
What's the main difference between zone and domain? It's confusing to me,I'm searching though,i got once,zone is a portion of domain. Can someone give example to clear things up? ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

A 1.2.3.5 All the above form a zone which would be called example.net. example.net, ns.example.net and www.example.net are individual domains within the zone. While that's true assuming there are no other records in the zone, consider what happens if you add this record: sub.example.net. NS ns.sub.example.net. Now the example.net domain extends below the bottom of the zone. Ahem... (puts on lecturer robes...) The domain name system is structured as an inverted tree, with a root at the top and other nodes below. Each node has exactly one parent, except for the root node, which has none. A label is the short name given to a particular node. A domain name is the full name of a node. It is equal to the name of the node and all of its ancestors, in order from the node itself to the root, left to right, separated by dots. A domain is a subtree of the namespace - a given node and any and all descendants. It is named for the node at the top (the apex). The entire namespace is a domain named . (which is how we write the name of the root node). Every domain name corresponds to a domain, although possibly a domain containing just a single node. A domain can be divided administratively into units called zones. A zone, like a domain, has a single node at its apex. The difference is, there can be a cut in the namespace separating a child zone from its parent. That is, a zone is equal to a domain of the same name (i.e. having the same apex) minus any child zones. For example, consider the following well-known domain names: . (the root) com. example.com. www.example.com. Each of these domain names except the last is the apex of a zone. All of them are the apexes of domains. The node named www.example.com. is a member of each of these domains, but only one of these zones (example.com.). That's because the zone example.com. is delegated (separated by an administrative cut) from its parent, com., although it is still a member of the com. domain. Is it clear yet?
