“it’s easy peasy” says guy who demonstrably already knows and has time to learn a bunch of shit 99.9% of people don’t have the background or inclination to.

People like you talking about IPv6 have the same vibe as someone bewildered by the fact that 99.9% of people can’t explain even the most basic equation of differential or integral calculus. That bewilderment is ignorance.

These people apparently had the time and inclination to learn a bunch of shit about IPv4, though.

"Easy" is meant in that context. The people acting like the IPv4 version is easy.

So your second paragraph doesn't fit the situation at all.
