Ipv6 : Ipv6 And Ipv6 Essay
10 November 2016
In every network there are Internet Protocol addresses that are used. With these addresses we have been using one for quite some time. That version is called IPv4. Because IPv4 was started in 1990s and our networks have grown considerably, there is a need to get something better. IPv4 has certain limitations because of it only being 32 bits. That is why it was upgraded, to try to extend the use of available IP addresses. This is why IPv6 is now being implemented and it alleviates the number of IP addresses because it grown from 32 bits to 128 bits. Now there is more IP addresses, so everyone can have their own IP address. Of course with switching over, one needs to know what are the other differences, security functions and vulnerabilities for using IPv6.
One of the main differences of IPv6 was stated earlier in that it has the capability in having 2128. That is a lot of IP addresses. IPv4 is written as “192.168.7.2”. It is separated into 4 1 byte decimal numbers separated by a period. IPv6 is written very differently. It is written hexadecimal wise “fe80::d4a8:2365:a3b9:b2f3b11”. If you notice that IPv6 is separated by colons and not periods. IPv4 is a base 10 set up while IPv6 is base 16.
People using IPv4 can use DHCP or static. IPv6 uses a different DHCP. It basically doesn’t require a server to obtain addresses. It uses a autoconfiguration that the router advertises.…
