I am sorry, two random Internet users in Korea and Germany, your IP addresses are simply special.

    A few years ago my old university finally went with NAT instead of handing out public IPs to all servers, workstations and random wifi clients. (Yes, you got a public IP on the wifi. Behind a firewall, but still public.) I think they have a /16 and a few extra /24s in total.

      Honestly there isn’t much reason to go with NAT unless you are looking to lease/sell IPs

      The sad part is that almost no universities do IPv6

        I kinda get why organisations don’t migrate.

        IPv6 just hands you a bag of footguns. Yes, I want all my machines to have random unpredictable IPs. Having some extra additional link local garbage can’t hurt either, can it? Oh, and you can’t run exhaustive scans over your IP ranges to map out your infra.

        I’m not saying people shouldn’t migrate, but large orgs like universities have challenges to solve, without any obvious upside to the cost. All of the above can be solved, but at a cost.
