Big technology companies and business leaders have begun debating lists of actions that could become as taboo as mustard gas or anthrax in the physical world, such as testing cyber-weapons “in the wild”, in computer networks connected to the outside world.

老师好，请问in computer networks connected to the outside world是介宾in computer networks +后置定语构成状语呢，还是介宾in compute+wild同位语+后置定语？
