MAC Address Lookup

This service offers a straightforward method to **identify the manufacturer or vendor of a network device** by looking up its MAC address or Organizationally Unique Identifier (OUI). It draws information from comprehensive and regularly updated public databases, including the official IEEE registry and the Wireshark manufacturer database, currently encompassing over **54,000 MAC address prefixes**. This ensures you receive accurate and current vendor details—such as their name, country, and MAC block information (e.g., MA-L, MA-M)—without needing to manage local database updates. For developers and system administrators, a **free REST API** is available, providing a powerful way to integrate MAC address and OUI lookup capabilities directly into applications and scripts. This can be invaluable for network inventory, security analysis, and enhancing device identification processes while respecting data privacy principles. Regarding your privacy on this platform, the website is transparent about its use of cookies. It employs **essential cookies** for basic site functionality and **tracking cookies** to understand user interaction, with the latter being activated only upon explicit user consent. Users are provided with clear choices to manage their cookie preferences, promoting control over their digital footprint. The operating entity's VAT registration in Italy (IT 02453050508) suggests operations are subject to **GDPR data protection standards**, offering an additional layer of assurance for users concerned about how their data is handled. While the tool processes the MAC addresses you input for lookup, its primary function is to provide information *about* those identifiers from public records, not to track your personal devices across the internet.
