MAC Vendor Lookup
Resolve one MAC address, an IEEE prefix, or a pasted list against a local copy of the official IEEE registration data. Nothing you enter is sent to an external lookup service.
Addresses to identify
Paste one per line, or separate values with spaces, commas, or semicolons. ARP-table rows are accepted when the MAC appears as its own field.
The registry file is served with this tool and searched in your browser. Lookup values do not leave this page.
