Häufige Fragen

What MAC address formats are accepted?
Any format with 12 hex digits is accepted, including colon-separated (00:1A:2B:3C:4D:5E), hyphen-separated (00-1A-2B-3C-4D-5E), or no separator (001A2B3C4D5E).
How does vendor lookup work?
The first 3 bytes (OUI) are matched against a built-in table of common vendor prefixes. Not all vendors are included.
