Frequently Asked Questions
What MAC address formats are there?
Common ones include colon-separated AA:BB:CC:DD:EE:FF, hyphen-separated, dotted AABB.CCDD.EEFF (Cisco), and raw hex AABBCCDDEEFF.
Does case matter?
Hex case is equivalent, but different systems have conventions (e.g. Windows uses uppercase, Linux often lowercase). The tool provides both outputs.
Is OUI vendor identification supported?
Currently focused on format conversion. OUI vendor lookup can be combined with a third-party database.
What if the input contains invalid characters?
The tool filters invalid characters automatically, keeping only hex digits. If the format is completely unrecognizable it will show an error.
