The packet ID field value = 20.The MF position of the marker field 1.The slice offset field value = 0.The following points are included in the second slice of the original IP packet.Packet ID field value =20 (indicates that this IP packet is a slice of the previous IP packet).MF position 0 of the Mark field (indicating that this IP packet is the last slice of an IP packet with ID 20).Slice Offset field value =1480 (indicates that this slice is "after" the 1480th byte of the original IP packet).Note: The slice offset field value is in units of 8 bytes. Therefore, for the second slice in this example, the slice offset field value is really 185 (1480/8) o1.4.3 IPv4 Addresses and Address Structure An IPv4 address is a 32-bit binary number that identifies a device operating at Layer 3 (e.g., identifies a host NIC or router interface). Typically, IPv4 addresses are represented in human-readable dotted decimal form: the address is first divided into four parts, each of which is an 8-bit binary number separated by a dot, and then each binary number is converted to a decimal number.
