Our IT department just got this excellent spam from an AI vendor. Apparently we have been running our own server room since 1862! I was not born yet, so I'm very curious what "servers" we were hosting back then. Maybe they should run their AI through another AI […] [Original post on ipv6.social]
Screenshot of a spam message that reads:

Gustavus has run its own campus server rooms since 1862, so | imagine the hardware has piled up across buildings over the years.

| am Peter Langford at PODTECH. We build datacenter management software with Al-driven monitoring. One university IT team cut unplanned outages 40%
rooms.

We could run the same read-only assessment for Gustavus, done in about two weeks. If it shows nothing useful, you owe us nothing.

Would a short reply be easier than a call to see If this fits?

Best,

Peter

Today I saw a post on Hackaday about "UDP broadcasting" and #IPv6. Only that it barely touched upon UDP or broadcasting, and mostly served to reinforce long-dead or never-true assumptions that devs tend to have #IPv6. One citation is to a "2020 rant" that can be summarized as: addr6 too long […]

Here is my somewhat regular, beginning of the school semester, post about #IPv6 vs #IPv4 traffic on our college campus. IPv6 traffic is still generally twice that of IPv4. Maybe a little more IPv6 now than this time last year.

Time for another very irregular regular update on #IPv6 compared to #IPv4 usage on a dual stacked college network. As you can see from the graph, for most of the past 24 hours, incoming IPv6 traffic is significantly higher than incoming IPv4 traffic. This has been the case for many years now.

Happy to be involved with this one. Should also mention the speed with which this published. 14 months from a dinner conversation to a published document is pretty wild (12 months in data tracker time!) datatracker.ietf.org/doc/rfc9872

RFC 9872: Recommendations for Discovering IPv6 Prefix Used for IPv6 Address Synthesis
On networks providing IPv4-IPv6 translation (RFC 7915), hosts and other endpoints need to know the IPv6 prefix(es) used for translation (the NAT64 prefix (RFC 6052)). This document provides guidelines for NAT64 prefix discovery, specifically recommending obtaining the NAT64 prefix from the Router Advertisement option (RFC 8781) when available.
