Enter any IP address and find out which domain names are resolving to it. Our reverse IP lookup tool is especially useful for spotting shared hosting environments and identifying co-located websites.
Understanding what else sits on a server is a powerful research technique. Use reverse IP data alongside our WHOIS tool to build a complete picture of a domain's hosting infrastructure and ownership.
Reverse IP lookups are widely used in SEO audits, competitive analysis, and cybersecurity investigations. Find out whether a suspect domain shares infrastructure with other known sites in just a few seconds.
FAQS
What is a reverse IP lookup?
A reverse IP lookup takes an IP address and returns a list of domain names that point to it. Unlike a standard DNS lookup where you start with a domain to find an IP, reverse IP works the other way around — starting with the IP to find associated domains.
Why would I need to do a reverse IP search?
There are several practical reasons. You might want to confirm who else shares your hosting server, research a competitor's infrastructure, investigate a suspicious IP address, or verify whether multiple domains belonging to the same owner are hosted together.
How many domains can share a single IP address?
On shared hosting servers, hundreds or even thousands of domains can resolve to the same IP address. Dedicated servers typically host only one domain or a small number of domains belonging to the same owner.
Can I do a reverse IP lookup on any type of IP address?
Our tool supports lookups for standard IPv4 addresses. You can enter the IP directly or look it up via a domain name — we'll resolve the IP automatically before running the reverse lookup.
How do I find the location of an IP or domain?
Use the IP Lookup or Domain Location tool. These tools map the IP address to a geographic location, ISP, and ASN, giving you a clearer picture of where the server hosting a domain is physically located.
Where can I see the DNS records of a domain?
Our DNS Lookup tool handles that. Enter a domain name to retrieve all associated DNS records including A, MX, CNAME, TXT, and NS records in a clean, readable format.
