DNS/DHCP Management Console
Subnets
Subnetting enables you to distribute host ids for a given netid to several
subnetworks. Subnet property pages enable you to set and modify parameters for
a specific subnet. To access subnet property pages, select a Subnet object from
the DHCP directory window.
Addressing. Use this tab to specify the following parameters.
- DNS Zone for Dynamic Update. Specifies the DNS zone where dynamic
updating will occur. The specified DNS zone is then notified of any changes to
the subnet.
- Domain Name. Specifies the domain name that will be concatenated
with the hostname received from the client computer. This name will be given to
DNS during dynamic DNS update. The domain name must be part of the zone
specified for dynamic DNS.
- Subnet Pool Preference. Specifies the subnet pool to be used by
the subnet. This parameter setting is optional. Subnet pools enable the DHCP
server to assign addresses to multiple logical networks on a single physical
network. A subnet pool groups logical networks.
- Default DHCP Server. Specifies a default DHCP server that will assign
address ranges for the subnet. This server is also the only server that will
respond to BOOTP requests for the subnet.
- Comments. Provides an area for comment information pertaining to
the subnet. This field is informational.
Subnet Options. Use this tab to specify the following parameters.
- Lease Type. Specifies the length of time for an address assignment.
A lease type can be permanent or timed. Permanent leases never expire; the
client is assigned an IP address for an indefinite period. Timed leases are
defined in days, hours, and minutes. Timed leases expire, unless the client
renews the lease.
- Set Boot Parameter Options. Check the check box to specify the Server
Address, Server Name, and Boot File Name for the BOOTP service. This information,
provided at boot time, includes the address and name of a server the client
can contact for a boot image, as well as a boot file name.
Other DHCP Options. The DHCP Options tab enables you to modify, delete,
or select default options used by the BOOTP and DHCP services. Click Modify
to specify BOOTP or DHCP options. A list of options and their definitions can
be found in the Novell® DNS/DHCP Services Administration Guide.
IP Address Utilization. This tab enables you to get the details of
IP Address utilization of the selected subnet. For more information, see IP
Address Utilization.
