That won't stop applications from binding to the IP address explicitly and sending packets via the deprecated IP, though it may be sufficient for the OP's purposes.
I thought the test IP for Solaris IPMP was already marked deprecated but I've been known to be wrong...
If there's some requirement to absolutely prevent applications from using the IP address, Trusted Solaris Extensions should work.
hi
I need a dhcp congfigured to give some of my clients IP regarding their MAC addresses and rest should get any IP from same pool. I am not sure what to add dhcpd.conf to provide such a pool or group or class. I tried with this but seems not good enough.

if_mpadm
if_mpadm(1M) System Administration Commands if_mpadm(1M)NAME
if_mpadm - administer interfaces in an IP multipathing group
SYNOPSIS
if_mpadm -d | -r ifname
DESCRIPTION
The if_mpadm utility administers IP interfaces that are part of an IP Multipathing (IPMP) group. Currently, administration is limited to
offlining IP interfaces and undoing previous offline operations.
When an IP interface is taken offline, all IP data traffic that was flowing over the IP interface is moved to another IP interface in the
IPMP group. In addition, all UP IP addresses hosted on the IP interface are brought down, causing in.mpathd(1M) to stop probe-based failure
detection on the IP interface. As a result, an offline IP interface will not be used for any inbound or outbound IP traffic. Only IP inter-
faces that are in an IPMP group may be brought offline. If the IP interface is the last functioning interface in the IPMP group, the off-
line operation will fail.
When an offline operation is undone, any IP addresses hosted on that IP interface are brought UP and will be considered by in.mpathd for
probe-based failure detection. In addition, provided the IP interface is otherwise active (see in.mpathd(1M)), it will again be used to
send and receive IP data traffic for the IPMP group. Note that not all offline operations can be undone. For instance, in.mpathd may have
offlined an IP interface because its hardware address was not unique within its IPMP group. The ipmpstat utility can be used to determine
why an IP interface is offline, identify which IP interfaces in a group are being used for inbound and outbound IP traffic, and more; see
ipmpstat(1M).
OPTIONS
The if_mpadm utility supports the following options:
-d ifname Offline the IP interface specified by ifname. If ifname is not in an IPMP group, or the offline would cause the IPMP group to
lose network connectivity, the operation will fail.
-r ifname Undo a previous offline of the IP interface specified by ifname. If ifname is not offline, the operation will fail.
EXAMPLES
Example 1 Offlining an IP Interface
The following command offlines the IP interface under0, causing any IP packets that were being sent and received through it to be handled
by another IP interface in its group.
example% if_mpadm -d under0
Example 2 Undoing a Previous Offline Operation
Use the following command to undo the operation in the previous example:
example% if_mpdadm -r under0

cannot offline: no other functioning interfaces are in its IPMP group.
Description:
This message means that offlining the IP interface would leave the IPMP group without network connectivity.
cannot offline: not a physical interface or not in an IPMP group
Description:
This means that the IP interface is not an underlying interface in an IPMP group, and therefore is not eligible to be offlined.
