@labelswitcher Haha nice! Perhaps this is a sign that IPv6 is 3x more complicated than BGP.

The IETF working group for IPv6 maintenance is called 6man.

Despite my repeated emails, they REFUSE to acknowledge whether 6man is related to Five Guys.

Reader, I promise you: I will not let them dodge this question.

If anyone writes an RFC, plz can u thank me in it. I might not have contributed directly, but I still think it would be very cool & good if you could thank me anyway, as an acknowledgement of how nice I am (which is very nice indeed).

Catching up on half a year of Ivan Pepelnjak's blog (partly in research for an upcoming post of my own), and found this gem:

https://blog.ipspace.net/2024/04/ipv6-slaac-unintended-consequences/

...where he explains why someone's IPv6 neighbor cache was artificially filling up. Well worth a read.

Unintended Consequences of IPv6 SLAAC « ipSpace.net blog

One of my friends is running a large IPv6 network and has already experienced a shortage of IPv6 neighbor cache on some of his switches. Digging deeper into the root causes, he discovered: In my larger environments, I see significant neighbor table cache entries, especially on network segments with hosts that make many long-term connections. These hosts have 10 to 20 addresses that maintain state over days or weeks to accomplish their processes. What’s going on? A perfect storm of numerous unrelated annoyances:

To be clear - the new option might well be an excellent and much-needed replacement for the current choice. Nothing wrong with that.

But when people use "legacy" to refer to something currently in use, it always feels like a marketing trick. If the new option is good, then show us why it's good on its own terms. Don't play tricks with language.

PROTIP: Want to convince people that your tech is good? Simply call the alternatives "legacy" - even if people are still using it perfectly happily.

IPv6 is a replacement for legacy IPv4.

SD-WAN is a replacement for legacy MPLS (never mind that this isn't what MPLS means).

Our monitoring system is a replacement for your legacy monitoring system.

Coffee is a replacement for legacy tea. Dogs are a replacement for legacy cats. Try it yourself. It's a fun hobby, and it's free for you to try!

Today I Learned that IPv7 was proposed in 1993 https://www.rfc-editor.org/rfc/rfc1475.html

(It's not a successor to IPv6 - there were just a few "next gen" protocols proposed at the time. Still, it's funny to call it IPv7!)

I have to admit, AI has saved me a lot of time. Every time I start reading about some interesting new app or service or product and see that it has "AI", I immediately stop reading and don't waste any more time on that thing.
