Netcraft. Whois lookup and Domain name search. Techzoom.net - Welcome to techzoom.net. Beehive/CoDoNS DNS Survey. It is well-known that nameservers in the Domain Name System are vulnerable to a wide range of attacks. We recently performed a large scale survey to answer some basic questions about the legacy DNS: We present the results from this survey below in the hope of identifying problem spots in the Internet and thus improving the security of our common cyberinfrastructure. This study is based entirely on public data - all information available on these pages is also available to others with less-than-honorable intentions. We collected 593160 unique webserver names from the Yahoo! And DMOZ.org web directories. We then queried the legacy DNS for these names and recorded the chain of nameservers that are involved in their resolution. The name delegation data enabled us to answer some basic questions about DNS security.
