All Registered Domains Worldwide — Complete Database Download

The All Registered Domains Worldwide dataset from WebTrackly is the most comprehensive domain name database available for purchase. This massive collection contains over 272 million registered domain names spanning every top-level domain (TLD) in existence — from legacy gTLDs like .com, .net, and .org to hundreds of country-code TLDs (ccTLDs) and newer generic extensions such as .io, .ai, .app, and .xyz.

What Is Included in This Dataset?

Each record in the database includes the fully qualified domain name along with its TLD classification. The data is compiled from authoritative zone files, WHOIS aggregation sources, and proprietary crawling infrastructure maintained by WebTrackly. The dataset is delivered as a CSV file compressed in ZIP format, making it easy to import into any database, spreadsheet application, or data processing pipeline. The uncompressed file size exceeds 5 GB, reflecting the sheer scale of the collection.

This dataset serves a wide range of professional audiences:

• AI and Machine Learning Researchers — Training language models, building domain classifiers, and developing NLP systems that need real-world internet namespace data at scale.
• Data Scientists — Performing large-scale statistical analysis on internet infrastructure, domain registration trends, and TLD distribution patterns.
• Cybersecurity Firms — Threat intelligence teams use complete domain lists to detect phishing campaigns, identify newly registered suspicious domains, and map malicious infrastructure.
• Market Research Companies — Quantifying the size of the global domain market, benchmarking industry verticals, and tracking the digital presence of competitors.
• Domain Investors — Identifying expiring or undervalued domains, analyzing aftermarket trends, and building valuation models using historical registration data.

Key Use Cases

The breadth of this dataset enables a variety of high-value applications:

• AI Training Data — Feed domain name corpora into transformer models for tasks such as domain generation algorithm (DGA) detection, brand-name similarity scoring, and URL classification.
• Natural Language Processing — Analyze naming conventions, keyword frequency, and linguistic patterns across hundreds of millions of domains.
• Domain Valuation — Build predictive pricing models by cross-referencing domain attributes like length, keyword presence, and TLD popularity.
• Market Sizing — Determine the total addressable market for any TLD or geographic region by counting and segmenting active registrations.
• Threat Intelligence — Compare newly observed domains against a known baseline to surface anomalies and potential threats in real time.
• Brand Protection — Monitor the entire namespace for typosquatting, lookalike domains, and trademark-infringing registrations.

Data Fields and Format

The CSV file contains clean, structured columns including the domain name and its associated TLD. The data is UTF-8 encoded, uses standard comma delimiters, and is ready for immediate ingestion into tools like Python (pandas), R, PostgreSQL, MySQL, Elasticsearch, or any ETL pipeline. The ZIP archive ensures fast downloads and efficient storage.
