DNS Open Source Tools Enhancement and Maintenance
2019 ARIN Community Grant Program Recipient Report
Overview
The Domain Name System Operations, Analysis, and Research Center (DNS-OARC) is a non-profit, membership organization that seeks to improve the security, stability, and understanding of the Internet’s DNS infrastructure. The ARIN Community Grant for the Open Source Tools and Enhancements Project has allowed DNS-OARC to develop, maintain, host and improve its suite of open-source tools for DNS measurement, telemetry and testing. This has enabled new releases of these tools, adding features, enhancements and bug fixes in response to requirements from the DNS community. It has additionally supported outreach to the DNS and operator community in support of these tools, and received recognition through collaborative development and additional grants being awarded for future enhancement of some of these tools.
Project Results
We have defined progress by new releases of our open-source tools for DNS measurement, telemetry and testing tools, adding features, enhancements and bug fixes in response to requirements from the DNS community. Below is a list of projects completed since the grant was awarded in August 2019 through July 2020.

- Both released, and tested to work on BIND9 and unbound. These are used to make DNSTAP support available in dsc.
-
-
DNS flag day 2020

Benefits to the Internet industry in the ARIN region
These open-source tools enable operators to better monitor and instrument their DNS infrastructure to manage and measure such things as IP address utilization across their networks. They will help support a more robust, efficient and secure Internet for their business and their users.
We have already had positive user feedback on multiple projects as organizations use these tools in their test and production environments. There is much involvement from the community with folks submitting issues, fixes and improvements, demonstrating significant community interest.
Our work was presented and demonstrated at the OARC31 and OARC32 workshops in Austin, TX and San Francisco, CA (co-located with NANOG) to ARIN region audiences during the grant period.
Furthermore, our ongoing maintenance work on dnsperf during the grant period has received recognition in the form of additional major grant funding to develop this software further, with a new engine for stateful connections, re-factoring, and DNS-over-HTTPS support. CZ.NIC selected OARC’s dnsjit tool as an important component of their open-source “DNS Shotgun” project, which has led to an ongoing technical collaboration to develop these.
