The WhoisXML Reverse IP/DNS API gives developers the ability to discover all connected domain names hosted on the same IP address. This allows detecting suspicious or dangerous sites, preventing overblocking, and conducting penetration testing. The API can also be used for SEO and brand protection purposes and to improve web hosting reputation. It covers close to 1.5 billion domains and subdomains with more than 1.2 billion IPv4 addresses updated daily. Both free and paid subscription plans are available. The free plan is limited to 100 queries per month.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
