Lesson Summary

The DNS database is indexed by name, so each domain (node) must have a name.

The hierarchical structure of the domain namespace consists of a root domain,

top-level domains, second-level domains, and host names.

When creating a domain namespace, you should use certain guidelines, such as

limiting the number of domain levels and using unique and simple names.

Zones provide a way to partition the domain namespace into smaller sections, so

a zone represents a discrete portion of the domain namespace.

A DNS name server stores the zone database file. Name servers can store data for

one zone or multiple zones. A name server is said to have authority for the domain

namespace that the zone encompasses.
