DNS, Identity, and Internet Naming for Experimentation and Research (DIINER)

Project Description

DNS, Identity, and Internet Naming for Experimentation and Research (DIINER) is a project designed to support new new research in Internet naming and trust. Our goal is to support research and ease transition from research to operational deployment, while preserving stability.

To meet this goal, we seek to unite researchers in Internet naming and identification around a new, shared research infrastructure providing:

  • Parallel DNS Resolution Evaluation to support safe testing of experiments within live, real-world deployed DNS,

  • A live instrumentation and measurement framework to share real-world DNS query and performance data with responsibility supported by technical and legal methods.

We hope to foster a collaborative research community with feedback between academia and real-world operations.

DIINER will leverage USC’s B-Root root DNS server and our background in privacy-aware sharing of network data.

We plan to release our tools as open source and support “research-infrastructure-as-service”


DIINER is supported by NSF/CISE as a CISE Community Research Infrastructure award award CNS-1925737, and it leverages B-Root with support from USC.
