With Ethernet, it is also possible, addresses of groups that are used to identify multiple network interfaces. Include such directions;

Broadcast addresses

In the majority of cases, six pairs (numbers and letters) that make up the Ethernet address usually are separated by hyphens. For example, we have the 07-06-A3-B6-faith. This is what makes it easier for one to distinguish the Ethernet address of other numbers. In some cases, two points can be used to separate the pairs. In this case, you can remove the zeros. It could, for example, the number of 8:0: A6: B4 are written: FC or would have something like this 0: 0:86: AB: 0f: cc. If you decide to zero to the left, "00" is "0", and this is what helps to eliminate six pairs.
