What is the difference between domain and zone?

[Mathias Körber]

I goes further than that. the *domain* cisco.com includes all subdomains,
whether delegated to other nameservers or not.

The *zone* cisco.com only includes the data that is in cisco.com's zonefile
for
that zone, ie the data in cisco.com, delegation and glue records for
subdomains etc.
A delegated subdomain is part of the domain cisco.com, but not of the zone
cisco.com.

Does that make it clearer?
