Supplementary Materials for: A Data-Driven Analysis of DNSSEC Self-Deployment among ICANN-Accredited Registrars

This repository contains the supplementary materials for the article “A Data-Driven Analysis of DNSSEC Self-Deployment among ICANN-Accredited Registrars.” It includes the full Python-based data pipeline, raw and processed datasets, documentation, and requirements necessary to reproduce all empirical results presented in the study. The dataset covers registrar-level and domain-level DNSSEC deployment observations, as well as pre-aggregated summaries by country and continent. The scripts follow a modular structure and can be executed step-by-step or as a complete pipeline via the included shell script. For more information, please refer to the README.md file included with this package. Note for reproduction: the continent field uses the code "NA" for North America. When loading the CSV with pandas, use keep_default_na=False and na_values=['']; under default settings, pandas parses "NA" as a missing value and silently drops all North American registrars.
