Configuring Special Features

This section describes how to configure NetWare 6 to use the following special features of Novell DNS/DHCP Services:

Configuring a DNS Server to be Authoritative for Multiple Zones

A NetWare 6 DNS server can be authoritative for multiple zones. There is no limit to the number of zones a NetWare 6 server can support other than those mentioned in Optimizing DNS Performance . Those limitations have to do with the total number of objects.

When you configure a zone, the Assign Authoritative DNS Server field in the Create New Zone task is the one that specifies the DNS server that will support the zone.

Configuring a Multi-Homed Server

A multi-homed server is a server with more than one IP address. In an Internet environment, a multi-homed server is a single server connected to multiple data links, which may be on different networks.

When using a DNS server with more than one IP address, you must use an address that is bound to the server, and that address must match the address used in the NS and A resource records for the zone.

NOTE:  An NS resource record specifies a domain name for an authoritative name server for the specified class and domain.

Configuring Dynamic DNS

Dynamic DNS (DDNS) provides automatic updating of DNS with Address and Pointer records for addresses and hostnames assigned using the DDNS feature. To use DDNS, the following configuration must already exist:

To activate the DDNS feature, complete the following steps:

  1. Select the Subnet object of the Subnet Address Range on which you want to activate DDNS and specify a zone in the DNS Zone for Dynamic Update.

  2. Select the desired Subnet Address Range and ensure that the range type is set to Dynamic BOOTP and DHCP or Dynamic DHCP.

  3. Set the DNS update option to Always Update.

  4. Click Save.
