IPv6 Address




The Internet Protocol Version 6 address (IPv6) determines the network nodes that are active in a computer network. This address contains 128 bits and is more prominent compared to the IPv4 addresses. Its structure is described in the RFC 2373 and can be characterized in three categories.

These include the Unicast, Multicast and Anycast. In the Unicast, the packet data which is transmitted to the unicast address is conveyed to the user interface that has been detected by the address.

In Multicast, all members of the multicast group actively participate in processing the packet. Anycast is quite different from the others and is a new category to the IPv6 address. In the Anycast, the packet data is conveyed to a single and the nearest interface set for the intended address.

The main advantage of the IPv6 over the IPv4 addresses is that the vast space that has addressing data to the route packets which are valid for the next internet generation. It can also support 3.4W1038 exceptional internet protocol addresses compared to the fourth version IP address. It is capable of availing unique addresses to every single device or node that is connected to the internet.

Reasons for IPv6 Addressing

There has been a growing demand for the internet protocol addresses which has been a motivating factor for the release of IPv6 addresses. The sixth version IP addresses are beneficial in terms of the large address space offered which is a distinguishing characteristic from the fourth version addresses. Most of the wireless devices and personal digital assistants would need to access the internet each providing its unique IP address.

IPv6 offers an extended address length which reduces the urge to utilize the different approaches like the network address translation. This is useful in preventing depletion of the address space available. The sixth version of the internet protocol addresses has the control data and addressing that allows routing of packets for the next internet generation. 


The notation in IPv6 addresses

The Classless Inter Domain Routing (CIDR) is useful in ensuring the IPv6 networks are denoted. A subnet or network using the sixth version of the internet protocol addresses will be assigned a progressive group of the IPv6. It is usually characterized by a power of two.

The separation of the bit sizes in a network prefix is denoted by (::/) For example, the network address 2001: cdba: 9abc:5678 will be denoted and presented as 2001: cdba: 9abc:5678:: /64. An individual host can also be denoted by a 128-bit prefix network. The Internet protocol sixth version allows the network to have an individual host and other categories.

IPv6 does not utilize the broadcast messages and have three scopes of operations. These include the Link-local, Site local and the Global.




The Link local is where the nodes are on a similar subnet while in site local the organization is the scope and is characterized by private site addressing. Global is characterized by the IPv6 internet addresses and it is the scope. The loopback addresses are special addresses in IPv6 and the scope will rely on the type of unique address.
