hi, would it be possible to insert some kind of 'privacy' flag into each data packet in IPv6 so that the originating IP address would be scrambled at each router hop? (kinda like how NAT works, but on internet backbone routers) websites and other services that would be afraid of 'attacks' could opt out and just drop such packets. just wondering if something like this is already in production or if it would be something interesting, because a lot of people are more and more concerned with privacy and do not want to be traced by their IP address. furthermore, this might help bolster net neutrality. i run a small search engine and can't compete with google/bing because a small handfull of providers (cloudflare, etc.) are blocking my legitimate crawler from millions of the top websites. matt
