What is a reverse IP lookup?

A reverse IP lookup takes an IP address and finds the domain names that point to that IP. This lets you see which websites are hosted on the same server or address.

How does the PowerSEOTools.online reverse IP tool work?

Our reverse IP lookup tool resolves your input to a public IP address and then queries a trusted external database to list domains hosted on that IP. Results are displayed in a clean, filterable list together with a summary of how many domains were found.

What can I use reverse IP lookup for?

Reverse IP lookup is useful for SEO audits, competitor research, checking for spammy neighbors on shared hosting, investigating security incidents and planning server migrations. It shows which other websites share the same IP address as your domain.

Does the tool work with both domains and IP addresses?

Yes. You can enter an IPv4 or IPv6 address, a domain name, or a full URL. The tool normalizes the input, resolves the host to an IP address and then runs the reverse lookup on that IP.

Are there any limitations?

Results depend on the external reverse IP data provider and may not include every possible domain. For performance and usability, the tool also limits how many domains are displayed at once. Private or internal IP ranges are not supported.

Free Online Reverse IP Lookup Tool

The Reverse IP Lookup tool from PowerSEOTools.online lets you see which domain names are hosted on the same IP address. This is especially useful when you want to understand shared hosting environments, investigate spammy neighbors, perform security checks or research a competitor’s infrastructure.

Why Reverse IP Lookup is Useful

SEO audits: Check whether your site shares an IP with low-quality or spammy domains.
Competitor research: Discover additional websites a company might be running on the same server.
Security investigations: Look for suspicious domains that appear to be hosted alongside a known bad IP.
Server migrations: See how many domains are currently on an IP before moving to a new provider.

How the Reverse IP Lookup Works

You enter a domain, IP address or URL into the tool.
We normalize and resolve the input to a public IP address.
Our server queries a trusted reverse IP database via HTTPS.
The response is cleaned, validated and shown as:
- A summary of how many domains were found.
- A scrollable, searchable list of domains hosted on that IP.
- A trimmed raw response sample for debugging and transparency.

Interpreting the Results

The number of domains on an IP can vary from a single dedicated site to thousands of small sites on a shared hosting server. Seeing lots of unrelated or low-quality domains doesn’t automatically mean your site is in danger, but it may signal that you’re on a crowded or low-end shared host.

For high-value projects or security-sensitive sites, you may prefer a dedicated IP or VPS where you control which domains are hosted on the address.

Limitations and Data Sources

Reverse IP data comes from third-party providers and may not include every single domain that exists on a given IP. Some providers also rate-limit requests, which is why the tool trims the output and enforces a maximum display limit. Private and internal IP ranges are blocked for safety.
