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, DNS broken, bad software. All of which are v4 faults projected onto v6. But my chief complaint is the idea that v6 subnetting has gone away? What?? How can that idea withstand a moment's thought? (1/n)
