  • Well good news. Because ipv6 has a thing called privacy extensions which has been switched on by default on every device I’ve used.

    That generates random ipv6 addresses (which are regularly rotated) that are used for outgoing connections. Your router should block incoming connections to those ips but the os will too. The proper permanent ip address isn’t used for outgoing connections and the address space allocated to each user makes a brute force scan more prohibitive than scanning the whole Ipv4 Internet.

    So I’m going to say that using routable ipv6 addresses with privacy extensions is more secure than a single Ipv4 Nat address with dnat.



  • I think people’s experience with PLE will always be subjective. In the old flat we were in, where I needed it. It would drop connection all the time, it was unusable.

    But I’ve had them run totally fine in other places. Noisy power supplies that aren’t even in your place can cause problems. Any kind of impulse noise (bad contacts on an old style thermostat for example) and all kinds of other things can and will interfere with it.

    Wifi is always a compromise too. But, I guess if wiring direct is not an option, the OP needs to choose their compromise.




  • Yeah, but they’re not. That’s the modern world. But also even if it was a web server there’s usually ways to advertise the IP for the app to connect to. I’ve seen other stuff do that. So getting an IP is easy. Once the app knows the IP and if you really want to allow connections from outside to your IOT devices (I wouldn’t) it could remember the IP and allow that.

    You really don’t need to give a fixed IP to everything. I think I’ve given 1 or 2 things fixed IPv6 IPs. Everything else is fine with what it assigns itself.



  • Hah. But to be fair, ATM did have a specific use that it worked great for. That is the move to digital voice circuits. The small fixed cell size and built in QoS meant that if you had a fixed line size you could fit X voice channels, and they would all be extremely low latency and share the bandwidth fairly. You didn’t need to buffer beyond one cell of data and you didn’t need to include overhead beyond the cell headers.

    ATM was designed to handle the “future” or digital network needs. But, the immediate use was about voice frames and that likely dictated a lot of the design I’d expect.





  • I’d go further than that and say that deciding to leave the house or not, are both gambles.

    But in the context of spending money with the only net result being you lose money, make money or retain the same money with no other goods or services provided in return. Then gambling is the primary attribute of that spend.

    Bookmakers and investments meet that criteria, your other purchases are not.
