There are two main network level requirements for device connectivity with Xcode: The network supports Bonjour The network supports IPv6 with link-local traffic It's likely that the network where you can't connect the devices to Xcode is missing one of those requirements, and you need work with the network owner to address those configurations. If the network owner here is a corporate IT department, the link above to TN3158 tackles a particular slice these configuration requirements for some VPN and security configurations, so your IT organization may get some value from reading through that document, though there are many other types of IT configurations that fall beyond the scope of that document. There isn't a way to configure a device connection with just an IP address, neither with IPv4 or IPv6. You're correct that was possible a long time ago, but the inner workings of how Xcode and paired iOS devices communicate has significantly evolved since that time. — Ed Ford, DTS Engineer
