I am studying about IPV4 header.
For some options, such as one that records route a packet has taken, 40 bytes is far too small, making that option useless.
What does this mean?
What I know?
IHL contains number of 32 bit words in IP header. Min value of IHL=5=20 bytes. Max value of IHL=60 bytes.
i.e Options=40 bytes.
How much byte do we need to record the route the packet has taken? Can you give estimation?
