Sry, I didn't see an os.macos.networking.tcp-ip or osx...   
      
   I am wondering if it is possible to make a TCP connection from an iPad to a   
   MacBook Pro while the MacBook is not connected to the internet.   
      
   I know how to set up the MacBook to create a private wireless network, and   
   have the iPad join it, and then write code to create and use sockets.   
      
   It works when Macbook is connected to internet via Ethernet, but when there is   
   no connection it has no IP address. I tried manually assigning it, but iPad   
   cannot see it.
