The value of the total length field is 100 bytes. To find the numbers of the first byte and the last byte of the current fragment, we can use the following formula: First byte = (offset * 8) - (HLEN * 4) Last byte = First byte + (total ...
WebThe IPv4 address is a 32-bit number that uniquely identifies a network interface on a machine. An IPv4 address is typically written in decimal digits, formatted as four 8-bit fields separated by periods. Each 8-bit field represents a byte of the IPv4 address. How many bytes are in a single IP address? WebThe first 20 bytes are the base header, the next 12 bytes are the options. Example: In an IPv4 packet, the value of HLEN is 5, and the value of the total length field is 0x0028. How many bytes of data are being carried by this packet?
