ipv4

I'm working on a project where I'm planning to implement custom read receipts at the IPv4/TCP layer by modifying the BSD networking stack. My goal is to detect if someone is harvesting data from my server by tracking whether packets are being properly received and acknowledged. What I've Done...

UPDATE: I may have actually solved this, by swapping the order so that the jail creates the RFC1918 address on that interface FIRST, and then creates the loopback interface second. Now this confuses me even more, since I cannot route using ipv4 from the host system on that FIB, but it is...

Recently I have started to DualStack my online services and wondered how many of us actually started/completed the conversion? Please share your experience/issues and future plans too..
