Seems that Ubuntu 20.10 has two (2) DNS caches: After disable/enable the network and the wifi connection, or rebooting the system, the problem was still there: All the system configuration was ok, but some addresses where like fixed somewhere.

DNS records are likely cached by your provider’s DNS servers so if you want to check if the DNS changes you made were successful you can interrogate a DNS server from your domain hosting service with dig: It you want Ubuntu to start caching dns I recommend installing pdnsd together with resolvconf. Nscd is buggy and not advisable.
