![]() ![]() Real Mac addresses usually start with zero (00) since they haven't got past 65536 different manufacturers yet. The mac address isn't routable over TCP/IP (the internet) so devices with the same mac address can exist on the internet at large. That doesn't mean to say they can't be changed or spoofed and often are. The first 3 bytes designate the manufacturer and the last three are a number given to it at manufacture by the maker. On a more involved level (which you don't really need to know for setting up routers and stuff) mac addresses are usually unique to a device and you can't have more than 1 of that number on a local (non routed) network. IP addresses on the other hand are now 4 bytes (until IPv6 happens) and almost always expressed in Decimal format as a number 0 - 255. Sometimes the letters are upper case, sometimes lower case, but never mixed. They are invariably expressed in hexdecimal notation (base 16, uses the characters 0-9 + A-F - each byte uses 2 characters since 16 * 16 is 256).

For example hexadecimal 2 is 0010 in binary, Now to convert further, I inverted 3rd bit, it means 00 10 will become 00 00, which represents value 0 in hexadecimal, so 52 became 50. Take first octet 52 and use second digit 2, convert this hexadecimal bit to binary. Here I am creating IPv6 Link-Local Address with network adapter MAC address (Network adapter can be physical or virtual), MAC addresses are 6 bytes (48-bits) in length, I will convert it to 128 bit IPv6 address, Here is the formula for the same, For example I have hexadecimal mac address here 52:15:5D:26:42:09, It need to be add ff:fe in the middle, so it will become 5 2:15:5D: ff:fe:26:42:09. Note: Link-local addresses are not necessarily bound to the MAC addresses. I received one query on one of the chat group I am part of asking if there is a way to convert MAC physical address to Link-Local IPV6 address using PowerShell, Infact I had worked on the same kind project of migrating from IPv4 to IPv6 and already written it long bank. ![]()
