pmimin on Oct 06, 2012
48 bits is the size of a MAC address, and is layer 2
32 bits is the size of a IPV4 IP address, and is layer 3 16 bits is the size of an address for the TCP header and UDP header, and supports up to 65K ports
In each of these cases, the address size is the same for both a “source” and “destination” address.
