We have tested the new site a few times during off-peak hours and the results are extremely promising! If you would like to help test our beta site, please Contact Us and let us know you are interested in the beta. Since we have been subject to abuse of our API from several large companies and smart phone app creators who have incorrectly implemented our API, we have essentially been DDoSed for the past few months.

There are many Web API’s available that can provide exactly the similar results, but you’ve to agree its fun and learning in creating your own solutions.First we would like to thank all our loyal users, especially the ones who have donated!.

The First call to the function would be slow, but from the next call, you have a local copy of the CSV file on your machine, which can be queried comparatively much faster to web requests.

You can run the function like in the below screenshot. I Took care of Local copy part in my PowerShell function like in the screenshot below

Make sure when the Powershell function runs for the first time, it creates a local copy of content in a File at a static location, which could be accessed to get MAC vendor prefix information locally for all Future function calls by avoiding the Web request which is slower.

Look up the MAC prefix from the content of reference file, and display the respective Vendor/Organization Following is the PowerShell function to get above done.

Web request above mentioned public Github URL and downloads the content in a reference file.

Later uploaded it in CSV format to a public GitHub repo here, from where it could be downloaded to any machine. I scoured and sanitized the file to reduce the size by 3 times so that it’s quicker in downloads and Lookups.

Once you have the information, filter out all unnecessary things and store them in a CSV or JSON format, so that it can be easily uploaded/downloaded from a Publically accessible Github repository.

After some searching on their website, I found MACAddress OUI (Organisationally Unique Identifier) file with Vendor-Prefix mappings in a CSV format and I downloaded it. Ok, during my graduation days we read somewhere that MAC prefixes are registered at IEEE (Institute of Electrical and Electronics Engineers), So how about checking their website first.

Now I want the list of Vendors registered for every such Prefix, but how to get it?.So if my MAC Address is ’48-4D-7E-E6-A8-47′ then the first 6 digits (Prefix) can be easily extracted like MAC addresses are stored/burned on the device during the manufacturing process and are designed to not to be modified.The first 6 digits (24 bits) of a MAC Address is called as ‘Prefix’, which are Manufacturers bits registered in IEEE database unique to a vendor, somewhat like in below format – and next 6 digits are Device unique identifiers, following are 3 formats used to represent a MAC address –.

Yesterday while troubleshooting a network issue, I realized that if I can know the vendor of a MAC Address, then I could understand if it’s a Dell Router, a VMWare virtual NIC or a Dell server then maybe it will make life a bit easy, like in the following example.
