What's up with those comments? Am I still on HackerNews or did I visit Reddit with some HackerNews theme applied?

Internet engineers pre-2000 had some idealistic, heavly mathematically proven ideas that still seem revolutionary today. Due to human nature, not everything got through, but IPv6 is the best of what we have and creating another standard would be XKCD 927.

Under every IPv6 discussion people all of sudden have the urge to manually assign numbers, need to remember their cousin's phone IP and MAC address, forget firewalls exists, argue that ISP fiddling with TCP+UDP selling it as "Internet" is a good thing or that "sender" field on the envelope is a huge privacy issue.
