OUI Lookup
Identify hardware vendors from MAC addresses — paste one or many, any format
Paste one or more MAC addresses in any format — colons, dashes, dots, or raw hex. The tool identifies the hardware vendor using the IEEE OUI registry, classifies the likely endpoint type, and links directly to CVE search results for the vendor. Works with partial MACs, full MACs, and bulk input. Randomized or locally administered MACs are automatically detected.
Accepted formats
→Colons, dashes, dots, or no delimiter
→Partial or full MAC — only first 6 hex digits used
→One per line, comma-separated, or mixed
→Results appear as you type
Confidence
High — vendor is unambiguous
Ambiguous — multiple product lines
Unknown — OUI not identified
Randomized — private MAC detected
