Answers to common questions about coverage, interpretation, and practical use of the dataset.
Because registry disclosure policies differ. Some TLDs expose detailed registrant fields, others redact them heavily, and some responses fail entirely. Empty cells should not automatically be treated as parser errors.
No. The site publishes snapshot files and documentation. The design goal is reproducible research and bulk analysis, not per-request online lookup.
The archive is smaller to distribute and easier to checksum as a release artifact. It also avoids treating a very large CSV as if it were a webpage asset to be parsed in-browser.
Yes, but usually as enrichment rather than a standalone verdict source. It becomes more valuable when joined with DNS, IP-to-ASN, certificate, or abuse data.
Use the build time and checksum in meta.json. If a result depends on a specific snapshot, the checksum is the clearest identifier.
The sample helps you inspect schema and value patterns quickly without downloading the full archive. It is useful for prototyping queries, tutorials, and parser checks.
Because a row with little metadata is not the same as a row that failed to collect. Preserving those distinctions prevents misleading downstream analysis.
Updates follow the project’s collection schedule and the underlying input list refresh. Each release should be treated as a new point-in-time artifact rather than an in-place mutable file.
