Apparently, a problem exists under HPUX when attempting to configure two subnets (using 128 as the netmask)

Two possible solutions:

Kernel update:

/usr/bin/adb -w /stand/vmunix \
/dev/kmem >> /tmp/adb_log 2>&1 << end
check_bcast_addr/W 0
check_bcast_addr?W 0
end

nettune:

/usr/contrib/bin/nettune -s ip_check_subnet_addr 0

I haven’t tried either solution yet…
