Delegating Zones for DNS
DNS provides the ability to divide the namespace into one or more zones, which can then
be stored, distributed, and replicated to other DNS servers. When deciding whether to
divide your DNS namespace to make additional zones, consider the following reasons
to use additional zones:
A need to delegate management of part of your DNS namespace to another location or
department within your organization.
A need to divide one large zone into smaller zones for distributing traffic loads among
multiple servers, for improving DNS name-resolution performance, or for creating a
more fault-tolerant DNS environment.
A need to extend the namespace by adding numerous subdomains at once, such as to
accommodate the opening of a new branch or site.
