Scientists at the San Diego Supercomputer Center who are analyzing traffic to one of the 13 Domain Name System “”root”” Internet servers found that the server spends the majority of its time dealing with unnecessary queries.

    DNS root servers provide a critical link between users and the Internet’s routing infrastructure by mapping text host names to numeric Internet Protocol addresses.

    Researchers at the Cooperative Association for Internet Data Analysis at SDSC conducted a detailed analysis of 152 million messages received on Oct. 4, 2002, by a root server in California, and discovered that 98 percent of the queries it received during 24 hours were unnecessary.

    Some experts regard the system of 13 DNS root servers, the focus of several studies by CAIDA researchers, as a potential weak link in the global Internet. Occasionally, all 13 root servers are attacked simultaneously; such attacks could potentially disrupt the entire Internet.

    CAIDA researchers will discuss their analysis of the root server and other cybersecurity findings with Clarke during his visit to SDSC on Jan. 28.
