Root Zone Archive

With the assistance of its members and friends (especially AFNIC, RIPE, Paul Vixie, Peter Koch and Paul Hoffman) DNS-OARC has assembled a historical archive of the DNS root zone dating back to July 1999. This Root Zone Archive is a part of our larger project, the Zone File Repository.

DNS Statistics Collector (DSC) - FAQ - What It Is, and Why You Should Run It! (More...)

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.

DSC - DNS Stats Collector

DSC (originally developed by The Measurement Factory and now developed by DNS-OARC) is a system for collecting and exploring statistics from busy DNS servers. It uses a distributed architecture with collectors running on or near nameservers sending their data to one or more central presenters for display and archiving. Collectors use pcap to sniff network traffic. They transmit aggregated data to the
presenter as XML data.

dsc is configurable to allow the administrator to capture any kind of data that he or she chooses. A sample configuration is included that captures the following data:

  • Query types
  • Response codes
  • Opcodes
  • Source addressess or subnets
  • Query name TLD
  • EDNS parameters
  • Known types of DNS "pollution"

DNSDump

DNSdump is a Perl script which capture and displays DNS mesages, much like tcpdump would, but purpose built. However, dnsdump does not currently support DNS over TCP.

DNSdump can be obtained from the Measurement Factory:

OARC Data Catalog

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.
