Reverse IP Lookup Tool
Discover domains hosted on the same IP or find the IP address of any domain.
What is Reverse IP Lookup?
Reverse IP lookup is a technique used to find all domain names hosted on a given IP address. It is useful for:
- Identifying shared hosting environments
- Checking for potential phishing or scam domains on the same server
- Cybersecurity investigations and reconnaissance
How Does It Work?
Every domain points to an IP address via DNS. By querying DNS records or public datasets, reverse lookup tools attempt to list domains that resolve to the same IP.
Limitations of Reverse IP Lookup
- Not all domains are publicly discoverable
- Private or enterprise IPs may host only one domain
- Some IPs are behind CDNs or firewalls
Example:
If a server at 192.0.2.1 hosts multiple websites, a reverse lookup might return:
- example1.com
- example2.net
- example3.org
Frequently Asked Questions
Can I find all domains hosted on an IP?
Only if the IP is part of a shared hosting service and public DNS records are available. Not all domains are visible.
Is this tool free to use?
Yes! This reverse IP lookup tool is 100% free and uses Linux tools directly on your server.
Is this the same as reverse DNS?
Not exactly. Reverse DNS finds a single PTR record. Reverse IP Lookup tries to find all domains hosted on the IP.
