Reverse IP Lookup
Reverse IP lookup is a technique that identifies domain names publicly recorded as hosted on a specific IP address. It reveals shared-hosting relationships that may point to related infrastructure or additional websites associated with a subject. Shared hosting alone does not establish common ownership or control, so each hostname association needs corroboration before it is treated as a link. Reverse IP helps investigators map infrastructure connections between domains and decide which relationships deserve further research.
