What is the difference between a DNS "zone" and a DNS "domain"? - Windows Server

Gurus, What is the difference between a DNS "zone" and a DNS "domain"? I've been studying DNS a lot and grasp the concept, but I want to hear "field" definitions rather than "book" definitions...

    A zone is a unit of tion/transfer/storage which
    consists or the resource records of one or more domain(s),
    and when more than one these are adjacent to form a (partial)
    subtree of the namespace.

    Good answer.

    A little more -- for many people there is a close correlation
    between what most people think of as a "domain" and the
    technical entity called a "zone."

    As Roger indicates, Zones are about "tion" (and storage
    or management) being all the records for a 'contiguous' portion
    of the namespace that are kept in one file (or equivalent), on
    one "set of DNS servers", and managed by one set of admins.

    For small zones/domains there is usually not much difference
    in scope, LearnQuick.Com is both my domain and the zone I
    manage.

    But technically so is .COM a domain (and a zone) but the COM
    ZONE does NOT include any of the subdomains like Microsoft.com
    or Dell.com etc.

    Those have been delegated, from .Com, to other DNS servers, run
    by other administrators in separate (child) zones.

    Microsoft and Dell are free to manage ALL of their records from
    that point down in one zone/file/server-set or they are free to delegate
    further zones for things like RandD.microsoft.com or US.dell.com.


    Repeating what "Roger Abell" said:

    Just to add to the "differences" (perhaps the confusion even):

    Technically in DNS terminology, even a MACHINE name is
    also a "DNS domain" -- this usage is not common in ordinary
    conversation, and isn't even very useful, but it's technically
    true.

    DNS Domain as I understand refers to a namespace eg.cisco.com and DNS Zone is the domain database(collection of records in that domain)
