Host Search

Discover subdomains and hostnames of a domain, with their IPs.

● Runs on our server
Discovers subdomains and hostnames of a domain, with each one's IP, via HackerTarget (free, limited daily quota). This is a different method than CT Search — combine both for the best coverage.

How it works

Our server asks HackerTarget’s host search API for every hostname it has seen under your domain and returns hostname → IP pairs. Without an API key the free tier allows a limited number of queries per day.
