Silent Push Domain Search helps you discover and investigate domains across the entire internet’s IPv4 space using powerful passive DNS, WHOIS, network, and pattern-matching data.
Important Note on Data Retention
Domain Search is limited to A records with a last_seen timestamp within the last 30 days. This provides a focused, high-confidence view of currently active infrastructure but means older or stale domains will not appear in results.
For broader historical or full WHOIS data (including domains older than 30 days), use Full WHOIS search instead. Many users notice significantly fewer results in Domain Search compared to Full WHOIS. This is expected behavior, not a bug
What you can achieve with Domain Search
Discover attacker infrastructure before it’s used in campaigns
Detect brand impersonation and typosquatting domains
Track when domains first appeared or last changed
Find domains linked to specific name servers, mail servers, ASNs, or networks
Search using custom regex patterns or detailed WHOIS information
Get rich metadata for fast analysis and pivoting
Tip
For the best experience with clean, visually rich results (instead of raw JSON), just use Web Search>Type your domain query directly in Web Search — you’ll get the same powerful data presented in a much more readable format.
