Packets vs. pitchforks
The world in which IPv6 was a good design
In a parallel universe IPv6 shines — back here, the comments riot
TLDR: A revived post says IPv6 only really made sense in a different, older network world, not the one we live in. Commenters split into believers and skeptics, questioning the “nuclear war” origin myth, asking how Wi‑Fi fits in, and pitching ID-based fixes — a lively fight over the Internet’s future.
A throwback post arguing IPv6 only makes sense in a very specific “old wires and buses” world just resurfaced — and the comment section lit up like a server rack at 100% load. The author claims the Internet’s new address system is a complicated fit for today’s reality, not the slam-dunk some engineers promised. Cue the Great IPv6 Culture War: true believers vs. battle-scarred pragmatists.
On one side, purists cheered the vision of a cleaner, future‑proof Internet. On the other, skeptics rolled their eyes at yet another “Any Day Now” promise and asked blunt questions. One commenter demanded: if Wi‑Fi doesn’t use the old “everyone yells on the same wire” protocol, how does it even work? Another torched the famous origin story, asking if the whole “built for nuclear war” lore was just a bedtime myth. Meanwhile, a third tried to thread the needle with a workaround: what if apps tracked a unique ID so connections survive when your address changes?
The drama didn’t stop there. Veterans dropped old threads and more old threads like receipts, the phrase “buses ruined everything” became a meme, and someone joked we’re living in the wrong timeline where IPv6 never quite shows up to the party. Verdict: hilarious, spicy, and surprisingly educational — with just enough chaos to keep you scrolling.
Key Points
- •The author attended an IETF meeting where TCP BBR was first presented and observed cautious optimism about the technology.
- •IPv6 was a major topic at the meeting, promoted as a replacement for IPv4 and a path to a more elegant Internet architecture.
- •The article questions IPv6’s complexity and references RFC 1710 as an example of a simpler approach centered on expanding IPv4 address space.
- •Historical telecom systems used physical circuit switching and later TDM-based virtual circuits, which did not require addressing between endpoints.
- •Early Internet designs on point-to-point links relied on IP addresses for routing, while LAN bus networks introduced broadcast domains and different link-layer considerations.
