MAC Address Generator
Random MACs with correct local, unicast and multicast flag bits.
“Locally administered” sets the second-least-significant bit of the first octet (as random MAC features on phones do); “global unicast” clears it, and “multicast” sets the lowest bit.

概要
Generates random MAC addresses in colon, hyphen, Cisco-dotted or bare formats, with the universal/local and group/individual bits set correctly for each mode.
Locally-administered random MACs — what phones use for Wi-Fi privacy — set the U/L bit; the tool reproduces that convention so addresses look right to other software.
