Frequently Asked Questions

See our FAQ for more answers.

Can I download sample files?

Yes. Download a sample domain list or a sample extended dataset.

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

Both cover the same 148,711 domains using Hetzner nameservers. A basic list is one domain name per line in a gzip CSV. A detailed dataset adds DNS servers, server IP, hostname, emails, phone numbers, and more. See the dataset format details.

How do I automate daily downloads?

Schedule automatic downloads with the NetAPI. See the API documentation for authentication and endpoints.

Are emails and phone numbers available for every domain?

No. We collect contact details from public websites when available. Many domains have no published email or phone, and we do not guarantee these fields on every row. Do not use the data for unsolicited bulk outreach.
