The Measurement Factory has conducted two surveys of Internet-connected domain name servers (DNS) on behalf of Infoblox. The surveys consisted of several queries directed at each of a large set of external DNS servers to estimate the number of systems deployed today and determine specific configuration details.
The survey results revealed that many organizations often disregard these critical systems, which perform the functions necessary to make their presence available and accessible on the Internet. The Internet Systems Consortium's BIND software, which performs the domain name resolution function, is often out of date, opening the door to malicious attacks. And, the systems are sometimes mis-configured, potentially compromising network availability.
Following is a summary of the significant survey results:
|BIND 9.3, 9.2, 9.1||57%|
|BIND 8.3, 8.2, 8.1||20%|
For more information, a press release and reports including methodology, complete results and all findings are available.
