Oh dear, this is a bit of a rabbit hole.

I can't resolve any of those names you listed, so let's try to find out
why...

$ dig +noall +authority ns virtualbit.it @dns.nic.it.
virtualbit.it.          10800   IN      NS      names.sulweb.org.
virtualbit.it.          10800   IN      NS      ns2.sulweb.org.
virtualbit.it.          10800   IN      NS      ns11.sulweb.org.

$ dig +noall +authority ns sulweb.org. @a0.org.afilias-nst.info.
sulweb.org.             86400   IN      NS      dns2.seflow.net.
sulweb.org.             86400   IN      NS      dns3.seflow.net.
sulweb.org.             86400   IN      NS      dns1.seflow.net.

$ dig +noall +answer dns1.seflow.net. dns2.seflow.net. dns3.seflow.net.
dns1.seflow.net.        14314   IN      A       94.198.98.168
dns2.seflow.net.        14330   IN      A       193.70.56.6
dns3.seflow.net.        14365   IN      A       144.217.99.49

$ dig +short dns1.seflow.net. dns2.seflow.net. dns3.seflow.net. |
  while read a; do dig ns sulweb.org @$a; done | grep status:
;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 14143
;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 41727
;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 19805

OK, so seflow.net is no longer hosting sulweb.org, which means domains
like virtualbit.it that depend on sulweb.org are offline.
