Internet is a universe broad system of computing machine webs which consists of big figure of smaller family, intercontinental, concern, rational, authorities webs etc, which all together carries assorted information interweaved together for sharing the information and includes the services like e-mail, file transportation and other web pages.

As the cyberspace use is increasing there is an address deficit. The job of the IPv4 can be solved by the new version IP version 6.

This essay besides deals with the crisis of IPv4, the drawbacks of IPv4 and besides the population of the cyberspace.

The benefits of the new version IPv6 is explained indepth and the expiration of the methods accessible for the development of IPv6.

INTERNET Population:

Internet population is defined as the figure of users around the cyberspace which besides includes the web traffic related to universe broad web ( World Wide Web ) and besides due to other utilizations of cyberspace such as equal to peer webs, e-mails, file transportations etc.

Internet population is really tough to specify as it is still turning to a good rate twenty-four hours by twenty-four hours. Today about three million community members have opted to portion the information like the web pages. These users surf the different web sites, take the

information and transportation it through the net. As the use of the cyberspace is increasing, its monetary value is diminishing in analogue. The growing rate of the cyberspace is increased because of the broadband development. The internet population is measured by utilizing different methodological analysiss. Many attempts are being made every twelvemonth to mensurate the cyberspace population as it changes often.

The analysis is made in many different ways like comparing the per centum of users in different states, comparing the parts of the universe etc.

The cyberspace users in the universe harmonizing to the universe parts surveyed in June 30 2010 is shown in a pie diagram as follows.

This is varied from the past old ages. There are some coutries which depend on the cyberspace to the maximal extent. The top 20 states with highest figure of cyberspace users is mentioned in the below figure.

The most recent user information comes from informations published by Nielsen//Net evaluations. CHINA stands in figure 1 place with 1,330,141,295 cyberspace users in the universe. POLAND bases in the least place with 38,463,689 cyberspace users in the universe. When compared to the past old ages there is immense addition in the cyberspace use. Harmonizing to this information China, India, Brazil and Russia are expected to describe for most of the growing.

The cyberspace has begun in 1969 with four host computing machine systems which has grown to 100s of 1000000s.

The cyberspace users in the universe by geographic parts is shown below:

INTERNET POPULATION MEASUREMENT TECHNIQUES:

The mensurating methods of the internet population are:

Active measuring

Passive measuring

Hybrid attack

Active measuring:

The web belongingss is straight probed by shooting packages required to do the measuring web. But this can non be used ever as there is a disadvantage with this measuring. The measurement packages may hold a negative impact on the public presentation received by other sorts of traffic.

Passive measuring:

In this measuring, the proctor web traffic is dependent on the presence of the suited web traffic. If in instance there no suited traffic on the web, the proctor web doesnot work. Sometimes it is really hard or impossible to pull out.

Hybrid measuring:

Hybrid measuring is a combination of both active and inactive measuring.

The cyberspace is an compeling installation available to 1000000s of people planetary. It is a universe broad publically accessible web of interrelated computing machine webs that transmit informations by package exchanging utilizing the standard cyberspace protocol ( IP ) .

The procedure of internetworking can be explained in three beds of protocols. They are

IP protocol

TCP and UDP

Application protocol

By the resources of the package exchanging device, the IP protocol is used to reassign the information. Harmonizing to internet universe statistics people are utilizing cyberspace. Every computing machine has its ain IP references which are fixed by the IP protocol.

IPv4 is the first version of protocol to be widely deployed. The IPv6 deployment is still in its babyhood. On the footing of the IP references, the cyberspace addresses is classified.

In a category system, IP references are grouped in to one of five different categories:

Class A

Class B

Class C

Class D

Class Tocopherol

Each of the four eights of an IP reference represents either the web part or the host part of the reference, depending on the Class A, B, C, D, E references are shown as follows.

Fig 1: IP reference formats

( Beginning from www.ciscopress.com )

Class A reference:

The reference is a Class A reference if the first eight ‘s first spot of an IP reference is a binary 0. With the first spot of the first eight being 0, the lowest figure that can be represented is 00000000, denary 0. The highest figure can be 011111111, denary 127. An reference can be called a Class A reference if its value is between 0 and 127 in the first eight. The two Numberss 0 and 127 can non be used as web reference and these two Numberss are reserved.

The Class A reference was proposed to suit really big big webs, merely the first eight is used to stand for the web figure. Classify A with 24 can with keep 16,777,216 executable references. While constructing routings an ID figure is necessary which is used to mention to the full scope scope of hosts, here the web figure is an ID figure. By acquiring the first eight we can cognize the web and the category of IP reference. Network Numberss look really much like IP references, but the two should non be confused. For illustration the reference which contains all 0 ‘s in the host part part is used as the web figure and can non be used as reference, an single node 128.0.0.0 is a Class A web figure. In general, a web reference uses the left most byte of its host ‘s addressing if the hosts fall within the Class A scope. The algorithm is applied in pattern through the usage of a web mask.

There are about 17 million host references available, Class A provides excessively many possibilities for one company. Even though it is likely to hold monolithic sums of the nodes in the web, the hosts can non work in the same group, so the subnet mask allows sub gauze, which breaks the big group of addresse in to smaller groups called as bomber webs. Without sub sacking it can be waste of holding available references, so the whole Class A is sub netted.

Class B reference:

Get downing with binary 10 in the first eight is called the Class B reference. Hence, in the Class B reference the lowest figure is represented as 100000000, denary 128. The highest figure in the Class B reference is represented as 10111111. This binary figure is the denary 191. An reference can be called as a Class B reference if it lies between 128 and 191.

The Class B reference supports up to 65,534 hosts. The medium size webs are represented by the Class B addresses. In this the first two eights represents the web figure, to lade the host part there are 16 spots.

Class C reference:

Get downing with binary 110 in the first eight is called the Class C reference. Therefore, in the Class C address the lowest figure is represented as 1100000000, denary 192. The highest figure in Class C reference is represented as 11011111. This binary figure is the denary 223. An reference can is called as Class C reference if its value lies between 192 and 223.

The smaller webs are represented by the Class C reference, ther frist three eights are used to match to the web reference and the last reference for the hosts. Class C reference supports merely 254 references. The Class A reference and Class B reference are ready to wash up, Class C reference are left over to be assigned for the IP webs.

Class D reference:

Get downing with the binary 1110 in the first eight is called the Class D reference. Therefore, in the Class D address the lowest figure can be represented as 11100000, denary 224. The highest figure in the Class D reference is represented as 11101111, This binary figure is the denary 239. An reference can be called as Class D reference if the reference lies between 224 and 239. The Class D addresses is besides called as Melticast references.

Class E reference:

The reference is said to be Class E reference if the first eight of an IP reference starts with 111. The lowest decimal in Class E reference is 240. The highest figure in the Class E reference can be represented with the denary 255. An reference can be called as Class E reference if it lies between 240 and 255. The Class E references are non used to turn to the hosts.

As the cyberspace use is increasing the reference traffic has been increased more. Because of this the bomber sacking undertaking is introduced which makes the big group of webs in to smaller bomber webs.

Subnet undertaking:

The sub net undertaking Acts of the Apostless as a antagonistic portion to the IP reference. The IP reference consists of a 32-bit figure that ranges from 0 to 4294967295. This means that the cyberspace can incorporate about 4.3 billion alone objects. To do such a big block easy the 32-bit Numberss is divided in to 4 parts of 8-bit Numberss each. This 8-bit figure is besides called as an ‘octet ‘ . The eight contains the Numberss runing from 0 to 255. Alternatively of 32 binary base-2 figures it is converted in to 4 base-256 figures.
