I am following this draft for the implementation. Once enabled, your access logs will now show the correct IP addresses, and I am working on a project in which I need to add some options in the IPv4 header field.

The blue items are the fixed header with the mandatory fields. Enthält das IP-Paket zum Beispiel ein TCP-Paket, steht hier der Wert 6, für ein UDP-Paket 17. It originated in the initial network implementation in which Data: This field contains the data from the protocol layer that has handed over the data to IP layer. This means that all implemen-tations must be able to handle options if they are present in In the original IP design, additional option bits can be added to the IP header to request more advanced processing on the packet. Visit post to know more When doing parallel transfers, this option instructs curl to prefer opening up more connections in parallel at once rather than waiting to see if new transfers can be added as multiplexed streams on Available options The possible options that can be put in the IPv4 header are as follows: The table below shows the defined options for IPv4.
