About Reverse IP Lookup
A reverse IP lookup answers a simple question: what other websites live on this server? Give it a domain or an IP address and iHACKER resolves the address, then lists the other domains that point to the same IP — the "neighbour" sites sharing that host. It also shows the hosting provider, organisation, ASN and location, and warns you when the address belongs to Cloudflare or another CDN, where reverse IP isn't meaningful.
What it's used for
- OSINT & recon: map an organisation's other sites and infrastructure on a shared host.
- Security: spot risky or malicious neighbours on shared hosting that could affect your site's reputation.
- SEO: check whether your IP is crowded with spammy domains.
- Migration & audits: confirm which domains move when a server changes.
How to use
- Enter a domain (e.g.
example.com) or an IPv4 address. - Complete the quick verification and press Lookup.
- Review the server's details and the list of domains — click WHOIS on any to dig deeper.
Frequently Asked Questions
What is a reverse IP lookup?
It takes an IP address — or a domain, which is first resolved to its IP — and finds the other domains hosted on that same address, i.e. the sites sharing the server.
Why do I only see one domain, or none?
The site may sit on a dedicated IP, or it may be behind Cloudflare or another CDN. When a domain resolves to a shared CDN edge, the IP belongs to the CDN and is shared by thousands of unrelated sites, so reverse IP isn't meaningful — the tool flags this when it detects it.
Is the list always complete?
No. Reverse IP relies on passive-DNS datasets that are never fully complete or perfectly current. Treat the results as a strong lead, not a guaranteed, exhaustive inventory.
Is it legal?
Yes. It only uses public DNS and hosting information and is a standard OSINT, security and SEO technique.
Do you store my searches?
Results are cached briefly on the server to keep the tool fast and within provider limits, and requests are rate-limited to prevent abuse. Lookups aren't tied to your identity.
