What is Reverse IP Lookup?

Reverse IP lookup is a technique used to find all domain names hosted on a specific IP address. This is useful for:

• Security researchers - Discover related infrastructure during penetration testing
• Domain owners - Identify who shares your server
• OSINT analysts - Map organizational infrastructure

How it works

We use passive DNS data from Profundis.io to find historical DNS records pointing to any IP address.
