Here is how mine is set up (bluring out IP's)I create my audience by saying Visitor Profile; user.isInIpRange contains "webRange" where isInIpRange is the Profile Script and webRange is the value that would be returned in the script. 

I just had to go through this exercise...see below:/^(192.236.17.44|192.168.1.1|192.168.5.2)$/.test(strIp);Separate it by a pipe as an OR statement.
