Hardly. The provider is welcome to provide their own nameserver as a
service, but I certainly can (and in this case want to) use another.

Also, since the machine is always in the same place, there's no need for
the nameservers to change unless I say so.

As for the internal domain name of my machine (and my network for that
matter), that should also be up to me to choose. This would not be
relevant for servers which need to have the same name internally and as
seen from the internet, but for a home machine it makes sense to set the
machine name and domain name independent of the provider.

See above.

It doesn't work because my provider's name servers do not.
