@@ -6,3 +6,7 @@ The web dashboard is built from a stack of Node.js, PHP, and nginx. The Node.js
 
 The docker stack also uses a network on the 192.168.37.0/24 subnet, and secures all traffic to be within this subnet. The dashboard can only be accessed locally at port 80 on 192.168.37.1 when the secure_api variable is set to true.
 
+Working on the network descriptor, and I think to make it easier on me i will use json output from ip
+The problem is that if an interface has multiple IPs, then I have multiple lines of data for IPs
+I think perhaps I will update my code to be aware of properties that may be arrays
+I do think this makes more sense than having multiple cards for a single interface...
