IPv6 Address Format

The very important feature of the IPv6 address is that it consists of the address space which is quite and rather larger than other addresses. They are 128 bits in length. It is amazing and very thrilling to know that this address has been supported by 6.8 billion people. It is similar to the number of atoms in a ton of carbon! It is now becoming popular day by day.

It is better to have longer addresses because they allow and permit the user to have systematic, efficient and effective allocation of addresses. The prefix has now been altered and modified as it renumbers the entire network to precede the further processing in a better way. Large subnet space and route aggregation makes the networking and routing to work in a systematic way.

The IPv6 addresses are 128 bits in length and have enough room for the individuals. They consist of the hexadecimal digits and colons like 2001:db8:85a3: 8a2e:370:7334. They are mostly and usually divided into two parts. The very first one is the prefix part consisting of the 64 bits. Second one is the host part consisting of the 64 bits. Users will come across three types of Ipv6 addresses named by unicast, anycast and multicast. Unicast address supports a particular interface. Anycast interface recognize a bunch of interfaces. Lastly, multicast delivers only single packet to large number of interfaces.

This address also notifies and informs the individual that which particular area of the network is valid and appropriate to carry out the proceedings. IPv6 addresses have different type of ranges or scopes like node scope, link scope or global scope. Some of the addresses are used for link local network while others for site local network. Hence, these addresses are minute by minute rather second by second in a sea of changes!
