Introduction to IP and IPv6 Seminar Topic:
Ip address consist of A network address and a host address. Eg.126.96.36.199 where number that is red is network address and number that is orange is host address. So what exactly we may think this IP stands for: A IP generally stands for Internet Protocol.
To manage this we generally used the IPV4 address space, but as time passed on their was thought that we would shortage of address space for IPV4 so IPV6 was developed
If we calculate the bits of Ipv4 it as follows:
Source and destination addresses are 32 bits (4 bytes) in length.
IPv6 address is 128 bits long and consists of groups of four hexadecimal digits separated by colons.
Eg. Suppose you have a website with some domain address . Say www.ademoexample.com then its IPV6 address would look like
3102:30f0:2001:61::2 ie 16-bit blocks are set to 0 in the colon hexadecimal format which is compressed to “::” where“::” stands for double colon.
What more in general was the reason to create IPv6.One was the reducing cost for end host so that appropriate address is assigned. Second is the better performance for the end host.
Ipv6 fragment packets which are counter IPv4 header does not identify packet flow for QoS handling by routers. Source and destination addresses are 128 bits (16 bytes) in length.
Since we see that host address play a crucial role in Ipv6.Thus the use of host address resource records in DNS is to map hostnames to Ipv6 address.
Now let’s see on how well this go with the current trend ,we say about 3G technology in mobile .The first question that comes in mind is, Do Ipv6 have been created keeping this in mind? The answer is yes since it works with latest 3G mobile technologies .This possible due to hierarchical mobility and better router optimization.
