IPv6: The Basics

by Caezar M

the reason we need IPv6 is because we have almostĀ used all of our Ipv4 resources. believe it or not there are a finite number of IPv4 addresses and over the years through some less than efficient assigning of IP addresses we come to the present day close to exhausting the supply of nearly 4.3 Billion addresses provided by Ipv4. So why is IPv6 any different? IPv4 came at a time when less than reliable internet connections made it difficult to transfer data intact so there is alot of redundency and out dated overhead in IPv4 addressed. IPv6 plays on the fact that the internet is more reliable and needs less redundency. so how many addressed does IPv6 provide? it provides about (3.4 * 10^38) addresses, or put verbally, 340 undecillion, and put logically an undecillion is 1 followed by 36 zeros. at a time when we thought that 3.4 billion addresses were unexhaustable IPv6 seems to provide a better alternative to this problem. by providing a massive number of addresses even with out poor allocation of addressed it looks like we are strapped for a long time.


i like this article because it talks about how the expansion of the internet grew beyond what we anticipated. we knew that the internet was going to be a great tool but we never imagined it would get to the point that we exhausted 3.4 billion addresses worldwide. with IPv6 we have a new “seemingly” un diminishable supply of addresses and it will be some time before i think we will ever run out again if ever we do. however with the expansion of peripherals, more web sites, wireless everything, who is to say that it wont happen. i cant wait to see IPv6 fully implemented because that and many other changes are comming this year and i hope to see them bring good things to the internet.

  1. Did this article mention if there would need to be a change in current hardware to completely implement the change to IPv6? Or is it completely a software change that is taking place with it (IPv6)?

  2. Most organizations haven’t been too eager to switch over to IPV6, at least not in their private LANs. Do you have any idea as to why that might be Caezar? I believe IPV6 has been around as a standard since 1998, and yet it hasn’t been adopted by the vast majority of organizations. Do you think that humans might have a tendency to wait until the last minute before they change? What I mean is, are we going to wait until the last IPV4 address is assigned to some company before we start giving out IPV6 addresses on a more frequent basis?

  3. Good article. At my old job my boss would always make me switch network settings to Ipv6 and he would get really mad if I forgot!
