In an ipv4 header the ihl is
WebThe IHL (Internet Header Length) field (4 bits) indicates how long the IPv4 packet header is, in 32-bit, or 4-byte “words”. The minimum value allowed is 5 which would be 20 bytes (no options). The maximum value possible is 15, for a packet header length of 60 bytes (allowing a maximum of 40 bytes for “options”). WebSolution The HLEN value is 5, which means the total number of bytes in the. header is 5 × 4, or 20 bytes (no options). The total length is 40 bytes, which. means the packet is carrying 20 bytes of data (40 − 20). Example: fAn IPv4 packet has arrived with the first few hexadecimal digits as. shown.0x4a5000028000100000102..
