Internet Protocol Version 6 IPv6 – Advantages and Compared to Internet Protocol Version 4 IPv4

ipv6 internet protocol version 6

Internet Protocol Version 6 – IPv6

Internet Protocol (IP) is a method of transferring data from one computer to another, using the net. That is, each computer has its own unique address known as an IP address and connects to the Internet. Data is sent from one computer (sender) to another computer (receiver), while passing through a bunch on the way such exchanges (called routes).  All access to the Internet network is based on this method, which means many such addresses as however are more than 6 billion on the planet.

Change

Period when something him from one system to another function … Our internet address in the world can compare with the zip codes of cities and streets in cities. In this case with the internet, zip codes of cities and streets have been replaced by computer devices that have the all around. Imagine how many numbers you have for just one person with a computer, smartphone, and now television and games console that accesses the Internet. But it works slightly edited., We have  internet access addresses and are linked to several types of such sets.

Set that we have here is to have savings in the use of such global Internet addresses for Internet access in the world is increasing at a rate according to previous calculations and internet  access  have about 2 billion people. IPv4 addressing method for the Internet network, until now proved as perfect solution and satisfy all the needs of the development.

But lately scientists and computer scientists involved in the development and maintenance of the technology estimate that 4 billion addresses will not be sufficient to connect the world in the story with IPv4. IPv4 calculated back in 1970, it was considered more than sufficient range of addresses for networking that can be spread without problem..  But the population of the country at that time was approximately 4 billion people, it was also very logical solution. It is also believed that not all can afford to buy a computer and connect to internet, considering the cost of computer and technological possibilities of interconnections.

IPv6

This method of addressing is composed of data (figure) with a range of 128 bits. In translation this means 340 billion, billions and billions … (3.4×1038 addresses ) unique addresses. Compared two types of IP addressing, IPv4 is set as  iPod device compared to Earth as a representative set of IPv6. Unless you have a better chance of connecting devices to each other, in their structure can contain letters, which is not the case with IPv4. For example, the IPv4 address looks like this: 203.0.113.24; while IPv6 looks like this: 2001:0 db8: 3c4d: 0015:0000:0001: acdb: kl21 and as you can see look quite different, but that is only appearance. Basically do the same. Most important is that IPv6 immediately kicks NAT (Network Address Translation) which reduces complication in communications with servers, modems, routers and similar devices which act as a filter to the global network.

Network Address Translation ( NAT) component of the Routing And Remote Access service, IP packets exchanged between the local network and Internet are both routed and re-addressed. This readdressing allows multiple client computers to connect to the Internet by sharing a single public address or pool of public addresses. With NAT, you can assign all your internal clients private addresses; only the external interface of the NAT computer requires a public address. NAT is a service built into a router that modifies the header information in IP datagrams before sending them on to their destinations. This functionality allows host computers to connect to the Internet by sharing one or more publicly registered IP addresses on the computer running the NAT service. So it saves the use of IP addresses to access the Internet, but for now it is used in IPv4, since the number of unique IP addresses is pretty exhaustive.

With IPv6 is allows approach where everyone can be unique address and also directly to each device be connected to the global Internet network.

Advantages

One of the most important advantages is the ability to connect directly to the Internet network without using a server that you need to regulate this connection. The device acts as a server for assigning IP address as the client access will be possible everywhere, ie the places where he has not been. Simplifying things and stepping auto configuration to address, the net can be even easier. Only the device should support IPv6 and that’s it. Security is another step forward in the future, which In the past plan and not think with such a horizon. If security in creating IPv4 applied only device that receives data, today we attack the device sends data attacks during the transfer of data and attacks on the data itself through the process of transmission. It is not planned in the model IPv4, but IPv6 is now resolved in a better way.

The so-called IPSec (Internet Protocol Security ) protocol contains three types of protection. Authentication Header (AH) protocol provides authentication and integrity of data, Encapsulating Security Payload ( ESP) protocol where they check the level of data privacy, Internet Key Exchange (IKE) where both agreed communication points to the way data exchange and simultaneously monitor the process of exchange / bargaining with the security can be generated and dynamically. In this way improves security in exchange of sending device and receiving device and protects the transmission of information from the application and it facilitated the path of applications as they now do not have to contain its own protection for the transfer to take place safely. We introduce security policies and administration would be much easier. This security allows development of software services and technology to ensure higher quality applications and much faster data exchange, from what we have so far.

Entering Multicast and  Anycast options and complements the work even more. Multicast allows large data transmission in hierarchical layout with only one interval. This type of schedule data transmission allows regulation of flow, which directly transmits some constant information (sound, video, news).  These data would be transmitted only as long enough, and you contributed to the strain on the network or blocking of the data to other devices. For example, if you see on your TV Internet Television (IPTV) and doing a few apartments in your building, then a certain amount of data book specifically for this kind of exchange that is built into the TV and nothing less or more. One server in the building can regulate access to the Internet and also will not allow requests on the Internet more than they could afford the device.

Prognosis

Today largely implement the new IPv6 addressing model that began intensively since 2008 onwards. Now at least clarify its existence in our operating systems ( Windows 7, Windows 8, Windows Server 2008 and 2008 R2, Windows Server 2012 ).
