Block 3000 IPs on Juniper SRX

Hello Guys,

​

I'm willing to block 3000 IPs on an SRX but I'm struggling with the best efficient way to do it.

I trick is block the address-set (address-group) in a policy but I need to define all the 3000 IPs in the address-group.

I'm planning to place all the IPs in a column of excel sheet and then just copy the command with incrementation

set security zones security-zone untrust address-book address Banned-IP-1 88.88.88.88/32

set security zones security-zone untrust address-book address Banned-IP-2 77.77.77.77/32

​

set security zones security-zone untrust address-book address-set Banned-Group address Banned-IP-1

set security zones security-zone untrust address-book address-set Banned-Group address Banned-IP-2

Does anybody have a better way?
