Comment on ISPs seem designed to funnel people to capitalist cloud services

  No they fucking don’t, that’s not what routers do.

    That literally is though? NAT stands for Network Address Translation. It’ll take you public IP and translate those packets to use your internal one.

    If your computer has an address that starts with 169, 168, or 10 there is a NAT somewhere in your network.

      That is NAT, yes. But that is only one small function that a router can perform, and not all routers have NAT enabled. You only need NAT if your ISP only allows you to use a single IP address.

      If your computer has an address that starts with 169, 168, or 10 there is a NAT somewhere in your network.

      That’s not actually true. I can create such a network without connecting it to the internet, no NAT. I can create a second network, again, no NAT. I can then use a gateway router that allows any node on the first network to reach any node on the second. That router is still not doing any NAT. It’s just passing traffic between two networks.

        Yeah you’re right, I was simplifying to the point where I was a little mistaken. I was assuming y5ou’re network was connected to the Internet and was just a standard residential setup, but this is a much better explanation.

      Have you ever chained three Cisco 2600 routers together and then successfully ping’d clients on each end? Do you know what BGP is? OSPF? Do you know the difference between routing and routed protocols?

      I know you don’t, because people who do don’t make the claims you’re making.

      Not really.

      And even as a network amateur I know that its
      10.0.0.0/8
      172.16.0.0/12
      192.168.0.0/16

      and 169.254.0.0/16 is not even routable so no dice with NAT.

      So someone can connect to you just with with a public IPv4 starting with 192.x.x.x

  That’s not the point of a router. It is one feature that most of not all now have, but it’s not their primary purpose.
