Reverse lookup is any method that uses non-personal information to find a person’s identity. Using phone numbers, property addresses, or email addresses are the most common types of reverse lookup. Typically, reverse lookup services will provide additional information about the person’s identity, including property addresses, relatives, and more. A new type of reverse lookup is DNS reverse lookup, which enables companies to find out who has been visiting their website. This information enables deeper analysis of potential customers and target audiences.
