A Reverse IP Lookup reveals all domains hosted on the same IP address. Enter any IPv4 or IPv6 address to see a list of websites sharing that server. This is the opposite of a DNS lookup, which finds the IP of a domain name.
Reverse IP lookup is useful in digital forensics investigations. It can help trace the origin of cyber attacks, identify the infrastructure used by threat actors, and uncover any connections between IP addresses and domain names involved in malicious activities.
Reverse IP lookup assists network administrators in managing and troubleshooting their network infrastructure. It helps identify all domain names hosted on a particular IP address, enabling administrators to track and manage their network resources effectively.
Reverse IP lookup can be used in competitive analysis to gain insights into the online presence of competitors. By identifying domain names associated with competitor IP addresses, organizations can analyze their competitors' websites, services, and online activities.
Reverse IP lookup can be used for research and data analysis purposes. By analyzing the domain names associated with specific IP addresses, researchers can gather information about website hosting patterns, network configurations, and other related data.
Reverse IP lookup is a process that involves finding domain names associated with a given IP address. It allows you to discover domain names and hostnames hosted on a particular IP.
Enter the domain directly into the search bar above this page and it will resolve the current IPv4 and IPv6 records for that website. The page performs the lookup for you and may also surface other hosts that share the same IP when available. Some websites use CDNs or load balancers, so you may see multiple IPs or anycast addresses rather than a single origin server.
A reverse IP lookup finds domain names associated with an IP address, while a DNS lookup finds the IP address associated with a domain name.
Reverse IP lookup can be useful in various scenarios. It helps with security analysis, website verification, digital forensics, brand protection, network administration, competitive analysis, and research and data analysis.
Reverse IP lookup itself is not malicious, but it can be used for malicious purposes if someone intends to gather information for unauthorized activities. However, it is a legitimate tool used for various legitimate purposes like security analysis and network administration.
Reverse IP lookup may not always be successful in finding domain names. Some websites or services may use shared hosting or content delivery networks (CDNs), making it difficult to determine the specific domain associated with an IP address.
Yes, you can perform reverse IP lookup programmatically by using our API.
A Reverse IP Lookup finds all domain names hosted on a specific IP address. A Website IP Address Lookup does the opposite — it finds the IP for a given domain name. Both are useful for network analysis and security research.
Yes. You can look up IPv6 addresses, but results may differ from IPv4 since many IPv6 servers don’t expose reverse DNS entries publicly.
Yes. Reverse IP Lookup uses publicly resolvable data and is safe to use. Just make sure to follow applicable laws and avoid using data for malicious activity.
Reverse IP Lookup finds all domains hosted on an IP address, while Website IP Lookup finds the IP address for a specific domain name. They work in opposite directions and complement each other for network research.
Enter the domain in the Reverse IP Lookup page to see its IPv4 and IPv6 addresses then visit our Whoami IP page to fetch your current public IP as seen by servers. Reverse IP Lookup shows the destination IPs for the website and whoami shows your source IP. View them side by side to confirm both ends of the connection detect CDN routing or proxies and troubleshoot IPv4 versus IPv6 reachability.
Results are generally accurate but may not include every domain. Factors such as shared hosting, CDN usage, and changes in DNS or server configurations can affect completeness over time.
