Another option you can try, if you are unable to access a website and get the ERRADDRESSUNREACHABLE error message is to remove the Wi-Fi network from your mobile device's saved Wi-Fi passwords list, i.e. 'forget' the network, and reconnect to it. To 'forget' the network, follow the steps below: Go to Settings and tap on Wi-Fi. The IE test involves sending two ICMP echo request packets to the target. The first one has the IP DF bit set, a type-of-service (TOS) byte value of zero, a code of nine (even though it should be zero), the sequence number 295, a random IP ID and ICMP request identifier, and 120 bytes of 0x00 for the data payload. The second ping query is similar, except a TOS of four (IPTOSRELIABILITY) is. Everything else gets a 'Destination Net Unreachable'. I have booted into recovery mode and reinstalled macOS Sierra and it still exhibits the same behaviour. My next step, a drastic one, is to wipe the drive and reinstall clean 10.12.2. Unreachable: Send an 'Unreachable' message to the sending host. Table: Process the traffic according to rules defined in an 'Action Table' You can define many Policy Rules.
