Frequently Asked Questions

A MAC address is a hardware identifier assigned to network interfaces such as Ethernet or Wi-Fi. It is typically written as six pairs of hexadecimal digits.
Setting this bit marks the address as locally assigned rather than vendor-assigned. It is the second hexadecimal digit of the first octet, set to 2, 6, A, or E.
Generated addresses are valid in format but may coincide with real or reserved addresses. Use them only for legitimate purposes such as testing and privacy.
