The dataset linked lists every active .gov domain name, providing a comprehensive view of US federal, state, local, and tribal government online presence. Each entry includes the domain name itself, the organization's name, city, state, and relevant contact information including email and phone number. This data offers a valuable resource for researchers, journalists, and the public seeking to understand and interact with government entities online.
This dataset, titled "current-full.csv" and hosted within the Cybersecurity and Infrastructure Security Agency (CISA)'s "dotgov-data" repository on GitHub, provides a comprehensive listing of every active .gov domain name within the United States federal government. Each entry meticulously details a specific government entity's online presence. The data is structured in a comma-separated value (CSV) format, allowing for straightforward parsing and analysis. The primary component of each record is the fully qualified domain name (FQDN), representing the precise web address associated with a particular government agency or sub-organization. Accompanying each domain name is a wealth of supplementary information, including the designated contact person for that domain, encompassing both their name and email address. This contact information serves as a crucial point of reference for inquiries or reporting related to the respective domain. Further enriching the data is the inclusion of the domain's status, indicating whether it is currently active and resolvable. This status designation allows for quick identification of functioning web properties versus those that might be deprecated or undergoing maintenance. Furthermore, the dataset incorporates the date on which the domain was initially registered, providing historical context and potentially revealing patterns in government website development over time. Finally, each entry features a unique identifier, meticulously assigned to avoid redundancy and ensure accurate tracking of each individual .gov domain within the expansive dataset. This comprehensive collection of data meticulously documents the online footprint of the U.S. federal government, offering valuable insights into the structure, organization, and accessibility of government information online.

Hacker News users discussed the potential usefulness and limitations of the linked .gov domain list. Some highlighted its value for security research, identifying potential phishing targets, and understanding government agency organization. Others pointed out the incompleteness of the list, noting the absence of many subdomains and the inclusion of defunct domains. The discussion also touched on the challenges of maintaining such a list, with suggestions for improving its accuracy and completeness through crowdsourcing or automated updates. Some users expressed interest in using the data for various projects, including DNS analysis and website monitoring. A few comments focused on the technical aspects of the data format and its potential integration with other tools.
The Hacker News post titled "Every .gov Domain" linking to a CSV of .gov domains generated a moderate amount of discussion, with several commenters exploring different facets of the data and its potential uses.
Several comments focused on the practical applications of the dataset. One commenter pointed out the possibility of using the data to identify government websites that haven't yet transitioned to HTTPS, potentially exposing sensitive information. Another user suggested leveraging the dataset to contact government agencies and offer cybersecurity services. The potential for building a comprehensive directory of government services was also mentioned, highlighting the data's usefulness for both citizens and businesses.
A thread emerged discussing the surprisingly high number of .gov domains, with some speculating about the reasons behind this large quantity. One commenter hypothesized that subdomains and development/testing environments could contribute to the inflated number, while another suggested that many agencies might maintain separate websites for different projects or initiatives.
Some commenters discussed the technical aspects of the data, including its format and how it's updated. One user questioned the use of a CSV file for such a large dataset, suggesting a database or API would be more efficient. There was also a discussion about the frequency of updates and the reliability of the data source.
The conversation also touched upon the broader implications of having a centralized list of .gov domains. A commenter raised concerns about potential misuse of the data for malicious purposes, such as targeted phishing campaigns. Another user highlighted the importance of maintaining and updating the list to ensure its accuracy and prevent its exploitation by bad actors.
Finally, some comments offered additional resources and tools related to .gov domains, including a website that monitors the adoption of HTTPS by government websites and a project aimed at improving the security and accessibility of .gov domains. Overall, the comment section provides a range of perspectives on the value and potential applications of the .gov domain dataset, as well as considerations for its responsible use and maintenance.
