Creating a variable for multiple IP addresses?

["Arthur DiSegna" <adisegna@xxxxxxxxxxxxxx>]

Hi,

What is correct syntax to have one variable equal more than one ip
address (not in order)? Is is possible or do I have to create a
different rule for each IP. 

For example I want to enable Samba on a Linux server but only want a few
members of network operations to have access to the server. 

NOC="192.168.0.1 192.168.0.2 192.168.0.25" 


Thanks in advance
