build passive DNS to get a list of domains for seized ns servers

[mthcht]

All available free services are insufficient. A good starting point would be scanning both the Tranco and Majestic Million domain lists with massdns for passive DNS records.

Combine with free informations retrieved from:

• Rapid7 FDNS dataset API
• https://viewdns.info/reversens/ API

• add the TOP1M domains to a database
• use https://certstream.calidog.io/ to add new domains in real time to the database
• use massdns to update the dns infos of each domains in the database
• calculate the necessary time for ~ 1M domains and scale if possible

I can do 400 million domains with massdns per day, need to schedule two days per month to update the list of seized servers with my server (not sure if it's worth it)
