Frequently Asked Questions
What is a Reverse IP Lookup?
Reverse IP lookup allows you to discover all domains that are hosted on a specific IP address. It's essentially the opposite of a standard DNS lookup, showing you domains that resolve to a given IP rather than finding an IP for a domain.
Why would I need to use a Reverse IP Lookup?
This tool is useful for identifying neighboring websites on shared hosting, researching competitors, investigating suspicious websites, or assessing the impact radius of server issues. Security professionals also use it to identify potentially related websites during investigations.
Are all domains on an IP always returned?
Not necessarily. Reverse IP lookups rely on parsed DNS zone files and other publicly available data. Some domains may use privacy features or configurations that prevent them from appearing in reverse lookups. Additionally, very large shared hosting environments may have too many domains to list completely.
How accurate is this tool?
This tool queries multiple data sources to provide the most comprehensive results possible. However, results may vary depending on the IP address queried and how frequently the underlying data sources are updated. For shared hosting IPs with thousands of domains, only a subset may be displayed.
Why am I not seeing any results?
Some IP addresses may not have any domains pointing to them, or the IP may be behind a CDN or load balancer that makes reverse lookups difficult. Additionally, some IP addresses (particularly those used by large hosting companies) may have privacy measures in place that prevent reverse lookups.
