- 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.
Here are some DNS-OARC development highlights for the past months. These updates are usually sent out on a bi-monthly basis but this one has been delayed a bit due to work surrounding OARC27 and holiday. [ Read More ]
A key part of DNS-OARC's mission is to develop, maintain and host various software tools for DNS data collection, measurement and analysis. You can find a list of these tools below, with their source code and development management at OARC's site on Github.
Here are some development highlights from the past two months surrounding packages, new features and a new tool. [ Read More ]
PacketQ, an analysis tool used to inspect DNS traffic, was developed by The Internet Foundation in Sweden, IIS, and maintained until 2014. IIS has now donated the program to the Domain Name System Operations Analysis and Research Center, DNS-OARC. [ Read More ]
With the assistance of its members and friends (especially AFNIC, RIPE, Paul Vixie, Duane Wessels, Peter Koch and Paul Hoffman) DNS-OARC has assembled a historical archive of the DNS root zone dating back to June 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:
Here are some development highlights from the past two months surrounding APIs, Check My DNS and releases. [ Read More ]
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.
