On the Internet they say no.
What if you send ARP requests knowing the IP range on the network you have not connected to? Will devices overwrite their ARP tables? If so, is it possible to intercept traffic? Or are they using some kind of encryption?

1If the Internet says no, why ask here? The answer is still 'no'. You can't send packets to a network you haven't connected to ... That's like asking, "How can I call someone's phone if I don't turn on my phone? What if I know their number? Will the call still go through?"– schroeder ♦Nov 17 at 17:09

What if I send arp requests on a broadcast and get the addresses of two devices and then send an arp to the router and say I have the device address or do I need the IP to send such a packet? Is it really impossible to get by with just one Mac address?– ushi YT-майнкрафтNov 17 at 17:29

While not connected to the network?– schroeder ♦Nov 17 at 17:32

1Don't you feel that you answer this yourself? You want to send something while not connected?– vidarloNov 17 at 20:39

1... connecting to a network is done at layer 1, not just layer 3... Please review the OSI Model...– schroeder ♦Nov 17 at 21:05
