Novell DNS Server as a Primary Name Server

Novell DNS Server as a Secondary Name Server (to a Non-Novell
Master)
the primary name server to determine whether the information it contains has
been changed. If the zone information in the secondary name server is older
than the zone information in the primary name server, a zone transfer occurs
and the secondary name server receives the zone information from the primary
name server.
If you are running a primary name server and providing DNS service for a
zone, the size or geography of your network might require creating subzones
within the zone.
Keep the zone data as a separate partition, and replicate the partition to all
places on your network where you have a name server for the zone. Doing so
enables independent replication of the zone data and also provides a degree of
fault tolerance in the case of server down time.
You must install the Novell DNS server as a primary name server to have
authoritative control over your zone and to take advantage of Dynamic DNS
(DDNS), the dynamic updating of DNS by DHCP.
When operating the Novell DNS server as a primary name server, you use the
DNS/DHCP Management Utility to make configuration changes. When you
operate a primary name server, the zone data can receive dynamic updates
from DHCP servers. Non-Novell secondary name servers can transfer data in
from the Novell primary name server.
If you plan to operate secondary DNS servers using Novell DNS/DHCP
Services software to a non-Novell master name server, one Novell secondary
name server must be specified as the Dynamic DNS (DDNS) or zone in
server. The DDNS server receives zone transfer information from the non-
Novell master server and provides updates to eDirectory. Other Novell
secondary name servers can then access the information within eDirectory.
Reasons for operating a Novell secondary name server to a non-Novell master
name server include:
