What Is The 48-Bit Ethernet Address Of Your Computer?
Before we discuss the 48 bit Ethernet address, firstly let us know about the Mac address in detail. The term Mac stands for media access control. This media access control is like a unique type of identifier that can be used to assign the NIC card. Normally this matrix is used in order to maintain communications with the other devices.
Now let us actually know what is Ethernet address is in detail. Normally a simple Ethernet address consists of 6 bytes these six B are nothing but the 48 bits.
This 48 bit Ethernet address will be presented in the form of hexadecimal that can be delimited by the symbols like dashes or Collins.
The below example shows the structure of the Ethernet address.00-01-42-A9-C2-DD. This is a presentation of the Ethernet address that is separated by the dashes.
00:01:42:A9:C2:DD, this presentation represents the Ethernet that is separated by the collins.
Usually, these Ethernet addresses are considered as a global unit type of addresses, Hare no of the two Ethernet devices will be able to share the same addresses and in order to achieve this address, the first of the three bytes of any addresses will be called as the OUI. This o u stands for the organisationally unique identifier.
Here the Hyderabad will be able to assign all these various types of manufacturers like Dell and HP. The other name for this type of address is called vendor ID. And the manufacturers will be able to assign all the remaining three types of B to the various special hosts.
This part is also called the host ID. Now let us take an example in order to understand this in detail. Suppose the OUI 00-01-42 will belong to Cisco. That means this Cisco can able be used in order to manufacture the network card and will help to assign the addresses to the 00-01-42-00-00-01.
This can also be able to assign the address to another card like 00-01-42-00-00-02. It represents that these types of addresses will have the same type of vendor ideas but it has different types of host IDs. Hence you can say that we have the 2 ^ 24 number of host IDs.
These internet addresses will also be considered as the two types of spatial bits. Now let us know each of these types in detail. The first type of spatial bit will indicate the address is the unicast address or it is the multicast address. This first meet is called the least important beat within all the important bites.
One of the types of multicast addresses is called the broadcast address. Other countries of a group or set of missions or devices that contain all the machine addresses. It is nothing but all these machines will be part of their broadcast group.
The second part of the spatial will indicate whether the addresses or truly globally unique or not. And it is also the second most least important byte.
