HI,
     I have set up my own IPv6 lab in my office . It consits of a
solaris , linux , AIX and HP machine.  Presently they are configured
for both  IPv4 and v6  but I want to have only IPv6 on those
machines . So can any one help me in disabling IPv4 on HP and even on
AIX.

Starting with an interface which has both IPv4 and IPv6 addresses
enabled, from the command line one could do:

# ifconfig lan1
lan1: flags=1843<UP,BROADCAST,RUNNING,MULTICAST,CKO>
        inet 192.168.1.123 netmask ffffff00 broadcast 192.168.1.255
lan1: flags=4800841<UP,RUNNING,MULTICAST,PRIVATE,ONLINK>
        inet6 fe80::230:6eff:fe4c:1c63  prefix 10
# ifconfig lan1 0.0.0.0
# ifconfig lan1
lan1: flags=1842<BROADCAST,RUNNING,MULTICAST,CKO>
        inet 0.0.0.0 netmask ffffffff 
lan1: flags=4800841<UP,RUNNING,MULTICAST,PRIVATE,ONLINK>
        inet6 fe80::230:6eff:fe4c:1c63  prefix 10
# ifconfig lan1 unplumb

(or ifconfig lan1 inet unplumb)

# ifconfig lan1
lan1: flags=4800841<UP,RUNNING,MULTICAST,PRIVATE,ONLINK>
        inet6 fe80::230:6eff:fe4c:1c63  prefix 10

and then to disable the IPv6:

# ifconfig lan1 inet6 unplumb
# ifconfig lan1
ifconfig: no such interface

I'm not entirely sure what the syntax would be in the
/etc/rc.config.d/netconf file.  Perhaps the "sam" command is smart
enough.  There may be more in the manpage for ifconfig.

You should make sure that all the applications you wish to run are
IPv6 aware of course :)
