You get yourself an AS and a registration and then talk to your ISPs about how to BGP peer with them. Read this to start wtih https://www.arin.net/resources/g

  Thanks. Same process as IPv4, but my question was more focused on the ??? magical last step of getting the ISP to advertise that route.

    It’s not magical, it’s exactly the same as IPv4, you either peer with them via BGP and advertise it yourself, or you give them an LOA to advertise it on your behalf.

    You need to ask your ISP either to announce it with their own ASN or peer with you if you have your own.

    Literally you just talk to your ISP. A support ticket or a technical phone contact. They'll either just do it for you or get you set up to announce your routes to them. You'll need an ISP that does actual business networking things, probably. I doubt Xfinity home service would do it for you.

It would be nice if someone made a wiki somewhere of which ISP's worldwide will do this on which plans. I'd really like to have two ISP's and BGP peer with both, so that if one goes down all my systems keep the same IP address and maintain connectivity. The whole idea of everyone having just one connection in a fragile tree-like structure seems against the original design goals of the internet.

More or less all of them with a business tier of service will do this. >I'd really like to have two ISP's and BGP peer with both, so that if one goes down all my systems keep the same IP address and maintain connectivity. The smallest subnet that is going to get advertised outside of your ISP (outside of the ASN you're in) is a /24, you can't have multiple ISPs and get that kind of address space for your personal stuff. The design goals of the Internet you're referring to are about networks not going offline, a global routing table with individual entries for every user is not sustainable.

With a bit of a redesign it would be. Most mesh networks tackle this problem. In the worst case, a routing table entry for every human in the world is only 8 billion entries, which would fit in RAM on a typical server today. And every optimization you do dramatically reduces that number (eg. make users who have similar network configs and peers have neighbouring addresses, allowing you to coalesce potentially millions of users into a single route)

            I'm just saying that rearchitecting the Internet / routers to support billions of routes would be a challenge, and it might just be too slow to have a routing table that big.
          • organsnyder 2y ago
            What about updates? Propagating routing table changes for even 8 billion devices (assuming each human has on average one device, which is quite the assumption to make) would be incredibly resource-intensive.

    Its no more magical than v4. In fact the BGP turn up call I usually have to do does both v4 and v6 at the same time.

  You only need an ASN (and at least for RIPE it's a requirement) if you have multiple upstreams.
