I saw the RFC for IPv8 recently
nitpick, but I would say “an RFC”, as there’s been a number of these over the years
you’ve gotten a couple responses so far, but I think the central issue is that “complexity” isn’t the problem with IPv6 (and one could certainly argue that IPv6 is actually simpler)–the problem is compatibility. This article lays out the issue very well, and also links to this article (which is a more specific look at the IPv8 proposal you refer to). Both point to the same conclusion, which is that fundamentally–on first principles–existing hardware does not know how to handle the upgrade, which will require some sort of dual-stacking, which is the issue IPv6 currently has. (Not its technical merit.)

we both thought of the same article haha
