What platform is this on? What hardware? What O/S?
Generally, you run some cluster/DR suite of software that manages failover. In those situations you might have node A and node B clustered. Node A is the production box and node B the DR box.
Both node A & B would have their "hardwired - never to change" IP addresses and the cluster suite presents a pseudo ip address to all clients. The clients only ever access this pseudo ip address (and don't know about the real ip addresses). When failover occurs the suite moves the pseudo ip address to the other node and the clients are none the wiser (apart from perhaps a few seconds hang).
So the question is; what have you got there?

NAME
pseudo - configuration files for pseudo device drivers
DESCRIPTION
Pseudo devices are devices that are implemented entirely in software. Drivers for pseudo devices must provide driver configuration files to
inform the system of each pseudo device that should be created.
Configuration files for pseudo device drivers must identify the parent driver explicitly as pseudo, and must create an integer property
called instance which is unique to this entry in the configuration file.
Each entry in the configuration file creates a prototype devinfo node. Each node is assigned an instance number which is determined by the
value of the instance property. This property is only applicable to children of the pseudo parent, and is required since pseudo devices
have no hardware address from which to determine the instance number. See driver.conf(4) for further details of configuration file syntax.
EXAMPLES
Example 1 A sample configuration file.
Here is a configuration file called ramdisk.conf for a pseudo device driver that implements a RAM disk. This file creates two nodes called
"ramdisk". The first entry creates ramdisk node instance 0, and the second creates ramdisk node, instance 1, with the additional disk-size
property set to 512.
