TCP/IP Stack Sends an IP Header Include Packet with IPID Being Zero but Overwrites Non-Zero IPID That You Supply

When you send a packet with the IP Header Include option turned on and set the IPID to zero (0) in the IP header, the Transmission Control Protocol/Internet Protocol (TCP/IP) stack sends the packet without generating a new IPID and overwriting the zero value with the new IPID. If you set the IPID to a non-zero value, the stack generates a new IPID, overwrites the value that you supplied, and then sends the packet with the generated IPID.
