Final Paper IPv4 vs IPv6

Many people do not realize it, although there are more that know that the world has an IP address that connects to the internet. When the internet was created they did not believe that IPv4 was ever going to run out of possible addresses that are able to be assigned to individuals and companies. Each IP address is assigned to either a wireless or wired connection. The history of IPv6 which is barely out there yet it does have a history already. There are many positives and negatives of both addressing Internet Protocols. Also I will talk about how DHCP servers can be used on IPv6.
To start off will talk about IPv4 and how the addresses became simplified to start off with. The addresses were bought out in clusters by organizations and when doing that companies have been able to lease out addresses to other companies so that we are not out of IP addresses. IP addressing was made so that people would be able to access out into the internet because their, were too many trying to access it at once it was slowing it down. This way the packets that were trying to be sent would be able to without issues. Transmission Control Protocol (TCP) was part of the beginning stages of IPv4. This took place in the 1970’s, then in 1981 they came out with Internet Protocol (IP). There were four different versions of IP and the version that is most widely known is the fourth. That is why IPv4 is called what it is called. IPv4 is made up of a 32 bit address on the dotted decimal system. There is a possible 4,294,967,296 addresses and yet we are slowly running out of possible addresses for the common public to use. There is one set address that is set up for loopback and that is that whole address line is taken up by loopback. Which means that you can ping back on for example to see if you’re connected to the internet. They actually started creating IPv6 after they attempted to create Ipv5 and realized that all they were doing with that was patching what was wrong with IPv4. So they started from scratch with IPv6 and made up a 128 bit address system that was made on the hexadecimal set up. The reason that they started creating IPv5 / IPv6 was because they realized that the amount of addresses that were offered would eventually run out. They just thought that it would take longer than they are seeing it happen. In most households now a days there are about 20 items that can hook up to the internet and take up an IP address. Those items can range from cell phones, computers, laptops, printers, gaming devices, televisions, tablets, and there are more coming out as we speak. When talking about IPv6 there is a security for the packets that would encrypt the data that is being sent just not where it’s sent from and where it’s being sent. The data that would be encrypted would be the inside information that you are sending to the end user. With IPv6 there will be 340 trillion internet address that will be available worldwide. This was set up so that every person would be able to have many addresses each. The issue with IPv4 is there are more internet users than IP addresses available and four times that with how many addresses that are being used. So many people share the same addresses that is why the internet can lag from time to time. The differences between IPv4 and IPv6 are very simple. The size comparison to start off with is extreme. Imagine the solar system for IPv6 and a small postage stamp for IPv4. While it is bigger it is less complex than IPv4. There are a lot of large companies that are already started using IPv6 permanently. Some of the companies
