Massive dataset update - added 40M new domains, reached 352M domains in the dataset overall
We’re excited to announce a major expansion of the AllZonefiles.io domain dataset.
Over the past few days (late December 2025), we integrated a new data source focused on ccTLD coverage, resulting in one of the largest single updates in our history.
- +40 million new domains added
- Total dataset size: 352 million domain names, up from 312M (gTLD + ccTLD combined)
- ccTLD coverage: nearly 114 million domains, up from 74M
The majority of newly added domains come from ccTLD zones, which are traditionally the hardest to discover and maintain at scale. This update significantly strengthens our international and country-level coverage.
Why This Matters. With this expansion, AllZonefiles.io now offers one of the most complete and comprehensive domain-name datasets available, delivering even more value to customers who rely on deep, global domain intelligence for research, analytics, security, SEO, and data-driven products.
More domains. More countries. More value.
