Address Objects in different Zones

Hi,

Based on the below configuration, the address object "cms01" is referred in different zones.

So my question is the address object is significant to the respective zones only or is it global ?

set address "Trust" "cms01" 172.16.0.99 255.255.255.255
set address "InterDC" "cms01" 172.16.0.73 255.255.255.255 "CMS"

regards

Rajesh
