Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      So many articles claiming how great DNS-Over-TLS is, but failing to mention that most implementations are poorly done, allowing the DNS server to track all the queries from an endpoint w/ TLS session resumption. It's a regression from stateless UDP DNS that needs to be addressed

      it's really an important regression ? Tracking is already possible via IP addresses for most users.

      Most IP addresses are shared between thousands of users.

          I'm curious to see reals statistics about that. In France, CGN on landline are very rare (and IPv6 is gradually deployed). For mobile networks, CGN are in place but when IPv6 will be in place, it will be one device == one IP address.

          Just a counting argument. Compare # of IPs not held for corporate/uni/etc. with # of end-user devices on the net.

          Virgin media and Talktalk in the UK provide fixed IP addresses even to domestic customers, at least those using fibre. I'm sure it's not just for me. The IP can change if they reconfigure their network. Still no IPv6, though. 😞

          Yes but that's a minority situation to be in, worldwide. All mobile ISPs are CGN. There's simply no other way to fit that many devices on IPv4.

          That's why I'm surprised neither has enabled IPv6, even optionally!

          FWIW @TalkTalk give dynamic IP's to residential customers although they have a lot of legacy ISP customers who may have static IP's assigned / pay extra for. @virginmedia residential are 'sticky' IP's (dynamic with long lease times). Would also like to see some progress from VM.

          I've got both TalkTalk and VM, TalkTalk just recently, and both are at least very sticky real IPv4s. The TalkTalk is fibre ("Ultra Fibre Optic") which might have made a difference.

          OT: My TalkTalk and VM links feed completely separate IP stacks on my main Plan 9 cpu server, with separate user-level stacks beneath those. VM side isn't quite right at the moment because the Google Wifi pucks keep crashing, disabling services.
