Im interested in thoughts for a scenario where you want to do small-scale multi-site activities, with site-to-site connectivity.

Here's a couple of constraints:

• you're not going to pay the money to get an assignment, you'll just have ISP global.

• your two or more sites will have different ISPs.

• You're doing VPN between sites instead of provider managed. The sites might be running some normal enterprise services like active directory, or other internal corporate norms.

• you might have the need for a backup Internet connection. Load balancing would not be required.

With the fact that the globals could change at a site, would you consider using ULA? Or just stick with global and update DNS in the event of change. I know there's a preference problem with ipv4 being chosen over ULA, so the ULA thing wouldn't be very easy unless you went straight v6.

If ULA, would you pattern/convention match the global in each site or create one organization wide ULA and assign it something like /48 per site?

What precautions do you take on gateways to ensure globals aren't used outside of the tunnel? ULA prevents this, but so does proper configuration I assume.

How would you do this?

I keep asking about ULA because I heard/read enough articles where the author says don't do it, but they seem to be geared at large enterprise or hosting where they would definitely get dedicated blocks, peering, etc. I'm interested in the little guy.

TIL that apparently capital one was assigned the entire 2630::/16 block...which is the largest assignment I've seen to date. Does anyone know of other absolutely massive allocations...are there even any others this large?

I've been using duckduckgo for years ever since I degoogled but I'm increasingly annoyed by its complete lack of IPv6 connectivity. I use NAT64 and so it works fine but it bothers me to use services that don't have v6. Does someone have a good non-google IPv6 search engine that's privacy respecting?

I wonder how bad search engines would penalize an IPV6 only site, is there any information on it?

Since I moved my server to ipv6 only federation broke. I'm guessing this server is acessible trough the cloudflare proxy, but the underlying server is unable to connect to mine

Edit:

This is what I get in the logs:

2023-09-27T19:17:23.955421Z DEBUG activitypub_federation::activity_queue: Activity https://lemmy.fbmac.net/activities/undo/506ed9a4-bfee-472f-8249-f802639eec8d was rejected by https://lemmy.world/inbox, aborting: Request error: error sending request for url (https://lemmy.fbmac.net/u/fbmac): error trying to connect: tcp connect error: Address not available (os error 99)

I think it kind of confirms, lemmy.world is unable to contact mine back.

What servers are really IPV6, so I can actually federate with something?
