When I type arp -abash in my shell, I get an output that looks like this:

What does all this mean? I poorly understand that I see domain names, IP addresses (internal IP addresses?), And MAC addresses. How to find the MAC address for the wireless router I'm connected to? Why are there so many entries here? I realized that for my computer there will be only one: one for the wireless router, one for the cable modem, and then maybe some other things up ... but I see other computers that are not mine. In addition, I do not see my computer. Also, can I somehow use this information to find the MAC addresses for wireless routers in public? What should I do if I cannot connect to the indicated public routers?
