How big is the MAC address space? The IPv4 address space? The IPv6 address space

Question

How big is the MAC address space? The IPv4 address space? The IPv6 address space? Suppose nodes A, B, and C each attach to the same broadcast LAN (through their NICs). If A sends thousands of IP datagrams to B with each encapsulating frame addressed to the MAC address of B, will C's adapter process these frames? If so, will C's adapter pass the IP datagrams in these frames to the network layer C? How would your answers change if A sends frames with the MAC broadcast address? Why is an ARP query sent within a broadcast frame? Why is an ARP response sent within a frame with a specific destination MAC address?

Explanation / Answer

1)

Similarly

MAC : 16^12 = 281474976710656 addresses
IPv4 : 2^32 = 4294967296 addresses
IPv6 : 2^128 = 3.4028236692093846346337460743177e+38 addresses.
