The MAC Address Lookup is used to find the real manufacturer or vendor OUI (Organizationally Unique Identifier) of your network card based on your network card MAC address. It also allows you to find MAC address records according to the company name.

MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communications on the physical network segment. It usually encodes the manufacturer’s registered identification number.
If you want to find the manufacturer a certain MAC address belongs to, enter your full MAC address or first 6 hexadecimal digits. This tool support most of the common formats such as 00-10-fa-c2-bf-d5, 00:10:fa:c2:bf:d5, 0010.fac2.bfd5, 00 10 fa c2 bf d5, or 0010fac2bfd5.
If you want to find a list of MAC address prefixes based on the manufacturer, simply enter the full or part of the company name, for example, apple or Apple Computer, Inc. The string entered into the tool is case-insensitive.
The data source of the MAC address database used in this tool is from IEEE.

Our list of vendors is provided directly from the IEEE Standards Association and is updated multiple times each day. The IEEE is the registration authority and provides us data on over 16,500 registered vendors.
Our API was designed from the ground up with performance in mind. We have stripped our API down to the bare essentials, optimized our servers, and organized our data so that whether your app is making 100 requests a day, or 100,000, you'll never be left waiting.
We have eliminated all unnecessary overhead from our systems. Simply send us an HTTP GET/POST request with your MAC address and we'll return the vendor. No registration or api key necessary for up to 1,000 requests per day.
We want you to feel comfortable building your systems around ours. Since launching in 2011, we have grown at an incredible pace. Today our API receives over 3.6 billion requests per year!
