What is DSC?
DSC is an application for collecting and analyzing statistics from busy DNS servers. The application may be run directly on a DNS node or may be run on a standalone system that is configured to "capture" bi-directional traffic for a DNS node. DSC captures statistics such as: query types, response codes, most-queried TLDs, popular names, IPv6 root abusers, query name lengths, reply lengths, and much more. These statistics can aid operators in tracking or analyzing a wide range of problems including: excessive queriers, misconfigured systems, DNS software bugs, traffic count (packets/bytes), and possibly routing problems.

One of OARC's functions is to collect and archive DNS-related data from its members. This data is available to members for research and operational use. Some of OARC's data is available through the secure member's portal. Other data is available via shell access from a read-only file server.
Members that require access to data must adhere to the guidelines outlined in the OARC Membership and Data Access Agreement.
