Bulk Vendor Lookup for Network Logs

Paste raw output from common network tools and this page will extract recognised MAC addresses, normalise each OUI prefix, and return the matching vendor where one is known. The CSV export is intended for network audits, inventory clean-up, asset reviews, and troubleshooting sessions where checking addresses one at a time would be slow.

Randomised or locally administered MAC addresses may not identify the original hardware manufacturer. Those entries can appear as auto-generated or vendor not found.
