My Fritzbox is assigned the IP address 100.64.x.x by my Internet provider.
My website can also be reached via this IP address on the Internet.

No.
It can’t.
No ISP will route to that 100.64/10 network over the Internet.
Your IP is ONLY accessible from that same network and from that same provider.
Other providers are free to also use that same network for thier clients.
[which means there may be many others with your same IP 100.123.19.126 connected to the Internet]

Then how do I access the Internet using that IP?
Because your ISP NATs your outbound connections with an IP (or a pool of IPs).
(Carrier Grade NAT)

Try Google: “What is My IP address?”

Yes, I changed the Internet provider from 1und1 to DNSnet

Ask DNSnet how much for a (static or even dynamic) REAL IP?

Hello,
I spoke to DNSnet.
You have switched my access to a public IP address.
Update of the certificate via Certbot now also works.
Many thanks for your help…

greetings
