Server Maintenance

Due to the abuse of our API from several large companies and smart phone app creators who have incorrectly implemented our API, we are essentially being DDoSed.

At the moment, we have restricted MAC address lookups to our home page.

Not to worry! We are currently spinning up new servers and will have a temporary fix ASAP along with an updated website containing more features soon. Feel free to contact me via email at with any questions, improvements, requests, ideas, or anything at all you may have.

Thank you!
