My understanding is that your accessory is presenting a network interface to iOS much like, say, an USB Ethernet dongle would. In that case I’d expect iOS to assign IP addresses to that interface as long as the interface claims that it’s up. You can prototype this with an USB Ethernet dongle: Connect the dongle via Ethernet to the Internet. And then connect it to iOS. Verify that iOS has network connectivity over the Ethernet. Disconnect it from iOS. Disconnect the Ethernet dongle from the Internet, but leave it connected to your switch so that the link status stays up. Reconnect it to iOS. You should see iOS bring up the interface with link-local IPv4 [1] and IPv6 addresses. Any app running on iOS should be able to communicate over that interface. For example, if you have a configure like this: iPhone | USB Ethernet | ----+----------------+--------------- isolated Ethernet | Mac | ---------------------+--------------- Wi-Fi to Internet Safari on the iPhone should be able to connect to a web
