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. 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. 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. 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.
