Question

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?

Answer 1

"Solution:

It is already give here, the HLEN value is 5. This HLEN value 5 declares the total number of bytes in the header which is equivalent to 5 × 4. We can also say it as 20 bytes. We can easily say now, the total length will be equal to 40  bytes and the packet is transferring 20 bytes of data (40 − 20)."
