Specifying a Dedicated IP Address

Bidirectional load balancing requires that you specify a
dedicated IP address for the load balancing group. This
address specifies a Network ID and a Host ID, and it must be
unique (not used elsewhere on the network). For example:
You can specify the dedicated IP address in the Create
Group or Group Properties dialog boxes. You cannot
specify the bytes for the Network ID; they are fixed. Specify
the bytes for the Host ID for various classes of subnets
as follows:
Class Byte 1
A
B
C
Byte 1
Class A Network ID
125
Class B

Class C
