It is interesting that you pose the question in regard to SPL instead of a data structure consideration.  But still, while array is a viable structure for many applications, SPL is not the only language that has to go to extra length to handle.  If you have a choice, and if you don't care much about front-end compute, hash is easier on SPL. (And again, easier in some use cases with other languages.)

I do want to suggest, though, you drop the nested listX.id node because that is redundant. (Lastly, I also recommend that you illustrate with compliant JSON.  This makes volunteers work easier.)

{"host": "test",

"list1" :{

                  "ip": "192.168.0.1",

                   "device": "laptop",

                   "value": 123

             },

"list2" : {

                   "ip": "192.168.0.2",

                   "device": "phone",

                   "value": 1223

                   },

"list3":   {

                   "ip": "192.168.0.3",

                   "device": "desktop",

                   "value": 99

                   }

}
