I will take your answer as "it is impossible to know GZ's IP from NGZ by default, unless it is properly documented somewhere".

That is what I expected, just to widen audience.

I have worked a not-so-decent solution, NG and NZG have the same MAC address, Based on the theory, You can filter out a list of ips which have same MAC address.

then ran remote ls command to check GZ's who has xml files in /etc/zones/

ssh IP1 'grep NGZIP /etc/zones/*.xml'

As I wrote earlier in post #3, this is by design. You are not supposed to get any information about any other zone from a NGZ.

This won't work in all configurations.
The various zones might use different network interfaces and so might have different MAC addresses.
Future network virtualization techniques (Crossbow project) will allow even zones sharing the same NIC to have different MAC addresses.
