MAC Address Inspector

What MAC address formats does this tool accept?

Any common separator style — colon (00:1A:2B:3C:4D:5E), dash (00-1A-2B-3C-4D-5E), Cisco dot notation (001A.2B3C.4D5E), or no separator at all (001A2B3C4D5E). Paste a messy value with stray whitespace and this tool still extracts the 12 hex digits correctly; it strips every non-hex character first rather than assuming a specific separator style.

Where does my MAC address go when I use this tool?

Format normalization runs entirely in your browser and never touches the network. Vendor lookups only send the first 3 bytes (the OUI) of your MAC address to our server, which checks a public vendor database — the rest of the address never leaves your browser and is never stored or sent to analytics.

What does "likely randomized (privacy MAC)" mean?

This address has the locally-administered bit set, a pattern used by iOS/Android/Windows MAC randomization — it may not reflect the device's real hardware vendor. This is a hedge, not a certainty: the underlying bit is a well-documented IEEE convention, but software can set it for reasons other than randomization too.

Why does this tool show 4 different formats at once?

Different tools expect different formats — Wireshark and most software use colon-separated, Cisco IOS uses dot notation, Windows commonly shows dashes, and raw/no-separator is common for programmatic use. Showing all 4 at once with one-click copy means you never have to reformat manually.
