What Are Three Parts Of An Ipv6 Global Unicast Address? (Choose three.)

Now, let us learn about the IPv6 global unicast address and different parts of this in detail. But what is the global unicast address?. The global unicast address, the first hextet that will be beginning with 2 or 3. These first hextet s globally unique and it is routable in nature. It is the public IP address that is similar to the public IPv4 address. we can see that the 2001:db8::/32, is the address reserved for the documentation. When we talk about the global unicast address assigning device and the address. The global unicast address range would be beginning with the 2 or 3, this is because the first 3 bits will begin with the 001 as shown in the figure below. If we convert that we can see the first hextet, if we convert the first four bits into the form of the hexadecimal digit. It will be 0 0 1 0 or it will be 0 0 1 1 2 or be a 3.

Now, let us learn about the parts of the global unicast address. So in the IPV4, it will be the 32-bit address. Here we will have a network portion and also the host portion. Now, we typically will subnet and in the subnet, we have to borrow bits from the host portion in. order to create our subnet., it is time-consuming and is a difficult process. But in IPv6 it will be an easier process. In the IPV6 we will be having an interface ID that is equivalent to the host portion in the iPv4. Here we also have a global routing prefix as we have shown in the figure. This is how our internet connects to the internet service provider. By the part of the network portion, it is a type of the subnet ID, the first 48 bits will be the global routing prefix, we then next allocate the next 16 bits which is between the 47 bits and the 64 bits for the interface ID. These Interface IDs are typically 64 bits. There is a simple reason for being the 64 bits. Suppose if we want to use a slack stateless address autoconfiguration for many devices. Here the host portion of the interface ID will usually be the 64 bits and the space between the global routing prefix which is getting from our provider and the interface ID will be our subnet ID, in this case, this will be the 16 bits. For suppose if we have a 64-bit interface ID will be equal to the 18 quintillion devices per subnet. And if we have the 16-bit subnet ID that will give the 65536 subnets in it. It is the most common global routing prefix allocation by the service providers. They typically will give most of the organizations with at least the slash 48 bits in it. In a lot of the IPV6 addresses will not worry about the conserving of the addresses space.
