they think they found the issue.
here is their reply:
"The Problem: In many Qualcomm-based (QCA) drivers, the Multicast Snooping (MCS) module is programmed to ignore "well-known" or "permanent" multicast addresses (reserved by IANA) for snooping purposes. It floods them to all ports to ensure compatibility with network protocols that rely on these addresses. Like the one that you are choosing here is just the permanent multicast address "ff05::1234".
The Consequence: Because the system doesn't "snoop" these addresses, it never learns which specific client wants the traffic. Without this "MDB" entry, the Access Point cannot perform Multicast-to-Unicast (M2U) conversion, which is essential for stable video/data streaming over Wi-Fi.
The Solution: Moving to the ff3x::/16 range (often used for SSM - Source-Specific Multicast) or other non-permanent ranges allows the MCS to intercept the join requests and create the necessary entries for optimization."
I then tried ff35::1234 and it did not work #IPv6 #multicast #cursed
This document discusses which multicast addresses should be used for documentation purposes and reserves multicast addresses for such use. Some multicast addresses are derived from AS numbers or unicast addresses. This document also explains how these can be used for documentation purposes. This document is not an Internet Standards Track specification; it is published for informational purposes.
My initial reflex of that thumbnail of cardboard with the words "no consent = no content" had me think about #multicast:

Especially as that's how @dentangle and @onepict have often described multicast.
Der Fall von Collien Fernandes schockiert viele. Erschreckend sind allerdings auch die Reaktionen: Menschen verteidigen jetzt ihr vermeintliches Recht, sexualisierte Deepfakes ohne Zustimmung zu erstellen. Und sie offenbaren damit, wie hartnäckig sich alte Machtansprüche halten.
Visited my parents today and noticed that my father uses #teletext on the TV to get live results for soccer matches. He's not using the internet for that. And I kind of like that idea, teletext is really neat, no pages cluttered with ads, dark mode by default, uniform font, no attention seeking animations.
And that made me wonder if there could be some useful protocols to proxy teletext to IP #multicast, of course :D. (afaik teletext pages are broadcasted round-robin?)
@Selfnet_eV, any ideas?
At IETF 125 there will be a meeting to discuss #multicast for AI networks.
They really do want to ruin *everything*
