A recent audit of AllZonefiles.io reveals it successfully indexed 81.9% of active domains across seven major ccTLDs, showcasing the effectiveness of modern data harvesting methods against the restrictive measures of sovereign registries.
Evaluating the integrity and depth of domain zone data is a critical requirement for threat intelligence teams, brand protection specialists, and market researchers. While generic Top-Level Domains (gTLDs like .com or .net) are relatively transparent, country-code Top-Level Domains (ccTLDs) are notoriously opaque. Sovereign registries frequently restrict zone transfers, enforce aggressive data masking to comply with regional privacy laws, or mask their metrics entirely.
To measure how effectively modern active discovery engines can bypass these structural barriers, we conducted a rigorous data audit of AllZonefiles.io. We compared their database capture sizes against the official public registry statistics published on June 25, 2026, targeting seven of the world's most prominent and historically restrictive ccTLD zones: .DE, .UK, .CN, .RU, .BR, .FR, and .NL.
The results reveal a stark contrast between defensive registry frameworks and advanced data harvesting capabilities.
Across these seven tier-one zones, the combined official registries account for approximately 72.3 million active domains. AllZonefiles.io successfully mapped and indexed 59.2 million of them, yielding an impressive 81.9% aggregate coverage rate across some of the most heavily guarded digital borders on the web.
| ccTLD | Country Region | Official Registry Size | AllZonefiles.io Capture | Coverage Rate | Audit Status | Official Data Source |
|---|---|---|---|---|---|---|
| .DE | Germany | 18,023,829 | 17,654,893 | 98% | 🟢 Excellent | DENIC Registry Node |
| .RU | Russia | 6,116,390 | 5,939,104 | 97% | 🟢 Excellent | CC TLD Statistics Node |
| .UK | United Kingdom | 11,500,000 | 10,974,923 | 95% | 🟢 Excellent | Nominet Reports |
| .BR | Brazil | 5,785,221 | 5,036,681 | 87% | 🔵 High | Registro.br Statistics |
| .FR | France | 4,494,489 | 3,827,177 | 85% | 🔵 High | AFNIC Observatory |
| .NL | Netherlands | 6,112,223 | 4,970,890 | 81% | 🔵 High | SIDN Labs Registration |
| .CN | China | ~20,000,000 | 10,800,000 | 54% | 🟡 Moderate | CNNIC Public Index |
Below is the visual distribution of the coverage percentages across audited country codes, demonstrating the database's precision across European and regional boundaries.
Additionally, comparing absolute volume highlights the variance between live authoritative registries and discovered records:
.de) and Nominet (.uk) manage two of the most structurally reliable and massive ccTLD frameworks globally..br), AFNIC (.fr), and SIDN (.nl), these zones feature intense data-masking mechanisms and localized registration rules designed to minimize public domain data visibility..cn) registry handles roughly 20 million active zones but remains largely closed off from traditional external crawling or automated extraction methods.The high coverage percentages achieved across these strict ccTLD zones demonstrate that AllZonefiles.io does not rely solely on static zone files or public registry directories. To circumvent registry limitations without exceeding operational inquiry limits, the platform's collection engine utilizes sophisticated recursive DNS scanning, continuous passive DNS mapping, and targeted vocabulary crawling to map out hostnames even when the native registry explicitly blocks zone file transfers.
For intelligence professionals who need visibility beyond generic .com environments, this audit validates AllZonefiles.io as an enterprise-grade resource for contextualizing global network assets.
