As answered by people managing Codility and AllZonefiles.io.
AllZonefiles.io's answer:
AllZonefiles.io brings together large-scale domain datasets from hundreds of gTLDs and ccTLDs in one place. Instead of dealing with many registries, access systems, formats, and update schedules, users can download normalized domain data from a single source.
Its key differentiator is breadth: AllZonefiles.io combines current and historical zone files, newly registered and expired domains, and enriched domain metadata covering 380M+ domains across more than 1,580 TLD zones.
AllZonefiles.io's answer:
AllZonefiles.io is designed for users who need domain data at scale without building and maintaining their own collection infrastructure.
Compared with services focused mainly on ICANN gTLD zone files, AllZonefiles.io also provides extensive ccTLD coverage, historical datasets, daily domain changes, and enriched domain information.
It is especially useful for teams that want ready-to-use bulk data for cybersecurity, SEO, domain investing, research, analytics, and data products.
AllZonefiles.io's answer:
The primary audience includes cybersecurity professionals, threat intelligence teams, domain investors, SEO specialists, researchers, developers, data engineers, and companies building products based on domain intelligence.
Typical users need to analyze millions of domains, detect newly registered or expired domains, study TLD markets, monitor domain activity, or enrich their own datasets and applications.
AllZonefiles.io's answer:
AllZonefiles.io started from a simple problem: obtaining comprehensive domain data is surprisingly difficult.
Domain information is distributed across ICANN CZDS, individual registries, ccTLD operators, public datasets, and other sources, each with different formats and access requirements.
AllZonefiles.io was created to aggregate, normalize, store, and continuously update this data so developers and analysts can focus on using domain data instead of building infrastructure to collect it.
The project has since grown into a large domain data platform covering hundreds of millions of domains and more than 1,500 TLD zones.
AllZonefiles.io's answer:
AllZonefiles.io is built primarily with Go, PostgreSQL, Linux, Docker, Nginx, and cloud/object-storage infrastructure.
The platform also uses custom data-processing pipelines for downloading, parsing, normalizing, comparing, and storing very large domain datasets and zone files.
The architecture is designed around efficient processing of hundreds of millions of domain records and frequent dataset updates.
