WebAn ARP packet for 48-bit MAC (like over Ethernet) is 28 bytes, see RFC 826.ARP does not use an IPv4 header but uses its own EtherType of 0x0806. ARP's size is less than the minimum payload for Ethernet of 46 bytes, so the frame is padded to the minimum frame size of 64 bytes (including 18 bytes overhead[*1]). WebThis corresponds to 1500 bytes which is the maximum frame size for Ethernet. NIC cards look at this field to determine which Ethernet standard is being used. If the field is less than '05DC', it represents a length field, and the frame is an IEEE 802.3 Ethernet frame. ... TCP/IP uses the Ethertype field to differentiate between ARP frames and ...
