In addition, the EUI-64 numbering system originally encompassed both MAC-48 and EUI-48 identifiers by a simple translation mechanism. The IEEE now considers MAC-48 to be an obsolete term. MAC-48 was used to address hardware interfaces within existing 802-based networking applications EUI-48 is now used for 802-based networking and is also used to identify other devices and software, for example Bluetooth. The distinction between EUI-48 and MAC-48 identifiers is in name and application only. The IEEE encourages adoption of the more plentiful EUI-64 for non-Ethernet applications. The IEEE has a target lifetime of 100 years (until 2080) for applications using EUI-48 space and restricts applications accordingly.

The IEEE manages allocation of MAC addresses, originally known as MAC-48 and which it now refers to as EUI-48 identifiers. This 48-bit address space contains potentially 2 48 (over 281 trillion) possible MAC addresses. The IEEE 802 MAC address originally comes from the Xerox Network Systems Ethernet addressing scheme. The b0 bit distinguishes multicast and unicast addressing and the b1 bit distinguishes universal and locally administered addressing. However, two NICs connected to two different networks can share the same MAC address. Network nodes with multiple network interfaces, such as routers and multilayer switches, must have a unique MAC address for each NIC in the same network. MAC addresses are formed according to the principles of two numbering spaces based on Extended Unique Identifiers (EUI) managed by the Institute of Electrical and Electronics Engineers (IEEE): EUI-48-which replaces the obsolete term MAC-48-and EUI-64. The address typically includes a manufacturer's organizationally unique identifier (OUI). Many network interfaces, however, support changing their MAC address. Each address can be stored in hardware, such as the card's read-only memory, or by a firmware mechanism. MAC addresses are primarily assigned by device manufacturers, and are therefore often referred to as the burned-in address, or as an Ethernet hardware address, hardware address, or physical address. As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.

However, the Free Version does what it claims it does.
#Mac ethernet full version
I wanted to give 5 stars when I first downloaded it, but Im afraid the Full Version isn’t working properly. I also tried reaching out to the creator on his website through the contact link, but the messaging/email section doesnt work when you click send. It still appears as if I have the 'Free Version' instead of the 'Full Version.’ I also restarted my computer after trying to restore and nothing changes. I then try to 'Restore Purchase' but nothing happens. When I click it, the 'preferences menu' opens up. It suggests that I look at the Full Version. It worked for a bit and when I closed out of the app to refresh something, it does not appear as if I made the purchase. I recently downloaded the Ethernet Status App and purchased the Full Version for $1.99.
