About MACProbe
MACProbe is an enterprise-grade MAC address lookup service built to help network engineers, IT administrators, security teams, and developers instantly identify the manufacturer behind any network device using its MAC address.
Our Mission
Every network-connected device carries a hardware identifier — its MAC address — that encodes the manufacturer within its first bytes. MACProbe exists to make that information instantly accessible, accurate, and reliable, whether you're auditing a network, investigating unknown devices, or building a security tool that needs manufacturer data at scale.
What Powers MACProbe
Our database is built on the official IEEE Organizationally Unique Identifier (OUI) registry, covering all three assignment block types — MA-L, MA-M, and MA-S — and is refreshed on a regular schedule to reflect the latest vendor registrations.
Who Uses MACProbe
- Network engineers auditing connected devices
- IT security teams investigating unknown or suspicious hardware
- Developers integrating vendor identification into their own applications via our API
- IT students and professionals learning about network addressing
