I need some help with an alert i have been stuck on. I have a DBCONNECT lookup that returns a value once a day. This value contains 18 IPs at the moment all separated by "," - for example value=1.1.1.1/24,2.2.2.2, 5.5.5.5/16.

I need an search i can create an alert off of if there is an IP added to this compared to when it was last ran. IE - search 1 at 6am had 5 IPs search 2 the next day has 6 IPs - alert.

right now i get the all the IPs in one field called "Value=" - looks like the below (ips changed for this post)

value="1.526.323.176/2,133.58.35.4/2,10.199.0.99/14

I basically need the alert to send our team an email letting us know an IP has been added and we should look into it.
