Refer To The Exhibit. What Is The Global Ipv6 Address Of The Host In Uncompressed Format?

Is the global IP address of the host in uncompressed format. Today let us learn about what actually the global address is in detail.

The global unicast address has the range 2000::/3. This global unicast address is very unique and also very routable.

It is also called the global IP address which is very similar to the ipv4 address.

This 2000::/3 is mainly an address that is used for the documentation and like education and many sorts of the things.

The global unicast address will begin with either 2 or 3, here the first three bits will be converted into the hexadecimal format.

Now let us know some of the parts of the global unicast address in detail. The global unicast address is simply the 32 bit address. It consists of two parts. They are network portion and the other one is called the host portion.

Here for the subnet portion, we will borrow the space from the host portion.

 The creation of the subnetting is a time-consuming process. But In the ipv6, it will be much easier. 

Here in the ipv6, it consists of an interface IP which is very equivalent to the host portion of the ipv4 address.

Here it also consists of the routing prefix. this part of the network portion is the same as how the internet service provider sees.

The part of the network portion consists of the subnet I’d. In the IP V6 global unicast address the first 48 bits will be called the global routing prefix.

Here the next 16 bits can be allocated to the subnet I’d.

Another part of the ipv6 global unicast address is called the interface Id. These interface IDs are normally 64 bits.

Here there is a specific reason for the 64 bits size of the interface Id. Here when we want to use the stateless address autoconfiguration. So the host portion of the interface-id will be 64 bits.

And the space between the global routing prefix is the one that we get from the provider and the interface-id will be the subnet I’d.

A lot of the ipv6 addresses will don’t have to be worried about the conserving of the address space.

The first half of the global unicast address will be of network I’d and the next half of the address will be called the interface Id.

Here the network I’d again be divided into parts that are global routing prefixes. This global routing prefix will be assigned bro the internet service provider.

This is the globally unique routing prefix. All the routers around the World will be using this prefix in order to direct the traffic to the network. And the last 16 bits in the network I’d be using as the subnet I’d. Unlike the ipv4 address, we do not need to borrow the interface portion of our address or any of the host portion of the address.
