Thank you very much for the technical insight. It makes clear why it is how it is and it is good to see that you can host Activitypub services on Subdomains… so the issue I thought that exists is not that big of an issue anymore. Also I love the discussion under your post, very interesting!

Thanks also to everyone else who replied!

Sure, ESXi would have been interesting. I thought about that, but I did not test it because it is not interesting to me anymore from a business perspective. And I am not keen of using it in my Homelab, so I left that out and use that time to do something relaxing. It’s my holiday right now :-)
