Domain Lists | FAQ

I downloaded the file, and it's too big. I can't open it in Excel!

Some popular zones contain tens of millions of records. After downloading the file, use 7-zip to extract it and ModernCSV to view its contents.

What is a basic domain list, and how does it differ from a detailed dataset?

Both formats include the same set of domains.

A basic domain list contains only domain names (one domain per line). The detailed dataset also contains additional fields, such as DNS (nameserver), IP addresses, emails, and phone numbers found on the corresponding websites.

You can download a sample domain list here 💾, and a sample dataset here 💾.

What are "active" and "new" domains?

When we say "active domains", we mean all delegated (?) domains. That is, they have at least one DNS (nameserver) assigned to them (i.e., they appear in the global zone files).

If a domain is not delegated, it is absent from zone files and from our lists. Non-delegated domains are a small fraction of all registered domains, so they can usually be ignored.

Since we update our data every day, we track which domains have appeared in or disappeared from the global zone lists. Based on this difference, we compile our lists of undelegated and new domains.

Why don't you provide daily updates for country code zones?

Many ccTLD zone files are not publicly accessible.

However, our crawlers scan hundreds of millions of domains each month and discover country-code domains through cross-references. After additional checks, these domains are added to our datasets, so most country-code domains are included. Because this data is collected indirectly, country-code datasets may not be fully refreshed every day.

What are domain lists by DNS provider?

In simple terms, these are lists of domains that use a particular DNS provider (e.g., Cloudflare). You can download (manually or via API) a list of domains that use one of our supported DNS providers. The file format is similar to the standard one (you can choose between a basic list and a dataset).

I need to set up a daily import of domain lists to my server. I don't want to download it manually every day. What should I do?

We provide an API that lets you download any selected dataset, or download a combined dataset across all zones at once. Read the full API description here.

The detailed dataset contains emails and phone numbers. Are they available for every domain?

Please do not use this data for unsolicited bulk email. It may be used for targeted outreach only after careful filtering and in compliance with applicable laws. Emails and phone numbers are collected from publicly available information on the websites associated with the domains in the dataset. Many sites do not publish contact details, so we do not guarantee that email or phone fields will be available for every domain.

Are there contract commitments, or can I subscribe on a month-to-month basis?

Subscriptions are billed monthly, and you can cancel at any time from your Dashboard.

What are some common use cases for NetAPI?

• Data Enrichment and Lead Generation: augment existing records with domain, infrastructure, and available contact details.
• Real-time monitoring of newly registered domains to help identify phishing, malware campaigns, brand impersonation, and other abuse.
• Brand protection: detect potential typosquatting and trademark infringement early.
• Domain investing (domainers): spot emerging keyword trends, track TLD popularity, and monitor portfolios.
• Market research and competitive analysis: track registration patterns, competitor portfolios, and regional expansion signals.
• Brand and affiliate compliance: monitor affiliates and partners for policy violations involving your brand.
• Fraud Detection and Risk Management: correlate domains and IPs, and compare with threat feeds/blocklists to flag anomalies.
• BI and analytics: ingest datasets into dashboards and data warehouses for ongoing reporting.
• Bug bounty / security research: monitor newly registered domains related to a target brand and investigate suspicious infrastructure.
• SEO & Keyword Research: identify newly registered domains tied to trending keywords and niches.
• Regulatory Compliance (KYC / AML): combine domain and IP signals to support partner or customer validation.
…and more. The data can be used in many other ways depending on your needs.

Can I integrate NetAPI datasets with my existing business intelligence or analytics tools?

Yes. Use our API for custom integrations. All API documentation can be found here.

Can I get a refund?

Unfortunately, no. We sell digital products that are non-returnable, so we do not offer refunds.

How can I request new features or provide feedback on the API?
