Apart from these, also ICANN's Cetralized Zone Data Service: <https://czds.icann.org/en/help> jaap Otherwise; the person to ask the question needs to have the "zone file information". nameserver list data feeds from the TLD registry operators, of every TLD they want to gather nameserver information for. For certain TLDs; this may be available -- for example, Verisign .com and .net "TLD Zone file access program". These data feeds are likely at substantially high application, approval, and paperwork requirements for acceptance, for each TLD, and substantially high cost for each TLD ----- therefore, not generally an option, so dailychanges or other commercial services will be your best option.. There is certainly no WHOIS or DNS query that will provide you this; which is essentially a search for database entries based on the IP addresses that NS record right-hand side values resolve to. > Regards > John > -- -JH
