A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

A good ISP that supports IPv6 will give you a /64 range. That's a huge number of IPs, 2^64. Easily enough for every device on your network to have a lot of public IPs. If you use Docker or VMs, you could give each one a public IPv6 address.

When every device on your network can have a public IP, there's no longer a reason to have private IPs. Instead, you'd use firewall rules for internal-only stuff (ie allow access only if the source IP is in your IPv6 range).

This is how the internet used to work in the old days - universities would have a large IP range, and every computer on campus would have a public IP.

Of course, you'd still have a firewall on your router (and probably on your computers too) that blocks incoming connections for things you don't want to expose publicly.

A good isp would give you something bigger than a /64 - /56 or /48. something that you can subnet.

wouldn't /64 still leave you with 64 bits for you to do whatever? Ipv6 has a 128 bit address. If you can do subnets with a small usable portion of 32 bits, then you certainly can with a full 64 bits

old post, but I so wonder why you got downwoted for saying it like it is. a good isp will give you a /56, the minimum best practice. a great isp will give you a /48 you'r router will also participate in the wan /64, but that is just the uplink, and not something that will be used on the lan. https://www.ripe.net/publications/docs/ripe-690/#4--size-of-end-user-prefix-assignment---48---56-or-something-else-
