Web Development

A lot of the educators I admire in the frontend web space seem to be either bowing out or dialing back their efforts: Axel Rauschmayer, Salma Alam-Naylor, Josh W. Comeau, to name a few.

Need to identify the manufacturer behind a MAC address?

MACAddress.com provides a free online MAC address lookup and a developer API for retrieving:

• Manufacturer and registered address
• OUI and assignment block type
• MAC address range
• Unicast or multicast classification
• Universal or locally administered status
• EUI-64 conversion and other parsed details

Developers can integrate it through the REST API, while AI agents can perform the same lookups through the MCP server using the same API key.

Feedback is welcome, particularly from developers working on networking, device discovery, cybersecurity, or asset-management tools.
