The internet will go down in waves as your DNS cache expires. Are you retarded? NSA has hooks in every central trunk in the country. They will just flood the network. Ever had a jabbering NIC on your network, it’s kinda like that only intentional and unstoppable.
Wrong. I don’t care if you plug a hardwire in to the same switch, know the ip address and the chink that soldered the nic. You’re not communicating over the wire in a packet storm.
