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

Both cover the same 11,482 domains using Otsuka (Alpha Mail) 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?

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.
