The fact you're reporting NXDOMAIN errors points to a different problem. A name server or servers are saying these TLDs don't exist, which is absurd. So there is a misconfigured server or some cache poisoning going on. That's got nothing to do with what name server software runs on ns.eu.net. Unless of course someone configured it to tell lies for these 4 TLDs.
Which is in fact what happened by accident. So ns.eu.net was telling lies about those TLDs for a short period until this was corrected. (More detail: It was configured with a root zone consisting of the bind root.cache file. So the server considered itself authoritative for the root but did not have a correct root zone file.) Lesson learned: Differences in nsd operation to bind need to be documented even more explicitly than they already are. Daniel
