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.
Real-Time DSC Data
Delayed DSC Data
C-root provides a 7-day delayed feed here.
Day In The Life of the Internet Traces
OARC manages the annual collection of traces from important and interesting DNS servers. OARC members can analyze this data on one of the OARC analysis servers. Visit the DITL page for more information.
Long-Term Query Collection
The collection is referred to as "LTQC" (Long-Term Query Collection) and it concerned itself just with priming queries, that is, the initial query that every resolver sends to a root server when it starts up in order to obtain an up-to-date set of DNS root server names.11 of the 13 root servers contributed data to this collection, including L-Root, the root server operated by ICANN. Data was collected between November 2009 and July 2010.
Deliberately Unvalidatable Root Zone
This was a study undertaken by DNS-OARC for the ICANN on the DNSSEC deployment at the root servers. Some of this work also produced data, a part of which has been graciously donated by RIPE.
Zone File Repository
OARC has been archiving copies of a number of TLD zone files on a weekly basis since March 2009. OARC members have access to the zone file archive on an analysis server. Please visit the Zone File Repository page for more information.
48-hour tcpdump (pcap) files
OARC coordinates the collection of DNS statistics with members utilizing tcpdump. Participants capture inbound DNS requests (only) for 48 consecutive hours, then store and upload the data to OARC systems as pcap files. Click here to view the list of members currently participating and the classification of the data collected.
ISC's Domain Survey
The Domain Survey attempts to discover every host on the Internet by doing a complete search of the Domain Name System. It is sponsored by Internet Systems Consortium, Inc. with technical operations subcontracted to Network Wizards. Survey data is collected and published quarterly and is available directly to OARC members. Full details about the domain survey may be found here.
Server Network Traffic Graphs
Traffic statistics for C, E, and F-root servers are available to members on the OARC member portal. The statistics are essentially MRTG graphs that include packets/bits per second (in and out), and current/maximum/average counters.
