90% of www in the same internet was hosted like this.
It feels like a loss that this is no longer the case.
It absolutely is
And its mostly the fault of ISPs
What did ISPs change?
They stopped giving people static IP addresses by default, which makes at home self hosting too hard for normies.
They never gave people static IPs by default in general. Done did if you were lucky but most didn’t. (In the UK at least.) Hence the existence of things like dyndns.
