That (the wrong IP address bit) has changed a bit recently- in S11, we have the facility to configure IP addresses from the global zone, and ensure that the NGZ cannot use any other IP addresses: see the "allowed-address" property in zonecfg for exclusive IP zones in S11. > Shared IP stack zones are simpler, at least to me, because the > non-global zones are much more constrained in what they can do. ymmv, but shared IP has its share of ugly "features" which may leave the NGZ with an incorrect perception of what exactly it can and cannot administer. And it makes it harder for the GZ to observe NGZ networking resource usage (or enforce controls on these). > (But I'm usually not concerned about things like this.
