Explanation :
Before you can set up many of theNetScreenfirewall, VPN, and traffic shaping features, you need to define
addressesin one or more address lists. The address list for a security zone contains the IP addresses or domain
namesof hosts or subnets whose traffic is either allowed, blocked, encrypted, or user-authenticated.
After you define anaddress.oran address group and associate it with a policy, you cannot change the address location to another zone (such as from Trust toUntrust). To change its location, you must first disassociate it from the underlying policy. Also keep the following in mind regarding to addresslists :

2.You can modify everything about an address book entry except its zone. 3.You can not modify an address object from the CLI, you must first delete it and the recreate it.
