Introduction to DNS-OARC

The DNS Operations, Analysis, and Research Center (DNS-OARC) brings together key operators, implementors, and researchers on a trusted platform so they can coordinate responses to attacks and other concerns, share information and learn together.

DNS-OARC has five key functions:

  • Information Sharing. DNS-OARC provides a trusted, shared platform to allow the DNS operations community to share information and data. Stringent confidentiality requirements and secure communications mean that proprietary information can be shared on a bilateral basis.
  • Operational Characterization. As Internet traffic levels continue to grow, the demand on root and other key nameservers will outgrow the current infrastructure: this year's DDoS attack traffic levels will become next year's steady state load. DNS-OARC measures the performance and load of key nameservers and publish statistics on both traffic load and traffic type (including error types).
  • Workshops. DNS-OARC organizes semi-annual workshops where members and the public are invited to give presentations on timely topics relevant to DNS both operations and research.
  • Analysis. Leading researchers and developers provide long-term analysis of DNS performance and post-mortems of attacks so that institutional learning occurs. A well-provisioned system allows members to upload traces and logs, and to perform their own analysis.
  • Tools and Services. As vulnerabilities and DNS problems come to light, DNS-OARC develops publicly available tools and services to assist with highlighting, diagnosing, and remedying such problems.

DNS-OARC participants fall into one or more of the following categories:

  • Operators of root, TLD, or large commercial nameservers who consume DNS technology and produce DNS services.
  • Implementers who produce DNS technology including software, appliances, and network elements such as load balancing hardware.
  • Researchers whose work has a strong DNS emphasis and who need access to trace and log data about the global DNS under both "normal" and "abnormal" conditions.
  • Security Providers whose companies offer products and services that utilize DNS information to improve the security of their customers.

To inquire about membership, or for any other questions, please contact the OARC Admin.

DITL Data Collection

A Day in the Life of the Internet is a large-scale data collection project initially undertaken by CAIDA and subsequently by OARC every year since 2006. This year, the DITL collection will take place in April. If you would like to participate by collecting and contributing DNS packet captures, please subscribe to the DITL mailing list.

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.

Root Zone Trends

The following graph shows trends in the contents of the root zone:

RSSAC 002

ICANN's Root Server System Advisory Committee has recently defined two standards, including RSSAC 002 , designed to obtain a baseline of the metrics for the Root Zone, specifically so that root operators can detect and mitigate any abnormalities in the performance of the DNS Root Server System as it continues to grow and develop.

DNS Looking Glass Information

There are a number of DNS Looking Glass sites around the Internet that will allow anyone to send a DNS query from that location. Looking Glasses are of particular use in the case of troubleshooting a problem with a DNS zone that is served from an anycasted service. In the event of a problem with the service, the view of a zone can be very different from distant places on the Internet.

Here is a list of some of the known looking glass sites around the Internet:
