COLLAPSE
IPv6 is the latest Internet protocol, replacing the IPv4. Although IPv6 is superior to IPv4 in several respects, its implementation requires new hardware and software technologies and expertise and, thus, financial investment. As a newly hired IT manager, you are proposing the implementation of IPv6. Discuss the argument that you would make to convince the management to approve your proposal. In responses to your peers, please discuss some issues migrating to IPv6 may cause.
According to the facts and the experiments, IPv6 has both advantages and disadvantages which cannot be ignored and as the new IT manager it will be hard to convince the management about the transition from IPv6 to IPv4. But, the key factor in convincing the management, is to assess the risks and benefits of both the versions of internet protocols and demonstrate a visualization between the two IP’s.
Advantages:
IPv6 has 128 bit addresses when compared to 32 bit addresses of IPv4 which results in a very large increase in the availability of IP addresses.
End to End Connectivity IPv6 eliminates the need for NAT which results in better connectivity in peer to peer networks.
Built-in Security IPv6 promotes interoperability between different internet protocols and their implementations.
Disadvantages:
IPv6 is not available for machines that runs on IPv4
The consumer costs is very high in replacing an IPv4 machine to IPV6.
There will be a lot of IP addresses to keep track of as the availability is more and we need resources to manage such a high volume.
If the benefits and limitations are closely analyzed, cost is the only element that looks as a limitation, but we have lot of benefits for installing IPV6.

IPv6 is the next version of the internet but what’s the value of actually using it?
COLLAPSE
IPv6 is coming, and our business needs to be ready. There are in total only 4.3 billion IPv4 addresses (Shawn, 2018). While that may have been fine in the 1980’s the simple facts are that, we are rapidly running out of old fashioned IPv4 addresses, and our business will benefit if we get ahead of this.
While in the US it is still relatively easy to get access to a single IPv4 address or even a /30 of addresses that can then be used for a NAT that will allow all of your IPv4 devices access to the internet, there is a massive market share -the rest of the world- that does not have it so easy. Thus, all of those potential customers will need to rely on some kind of translation service to access our resources.
On the other hand, there is a significant security advantage for moving all of your systems to IPv6. As Drake (2016) discusses, many traditional attack methods for performing reconnaissance against the entire IPv4 address space, IPv6 can offer a somewhat accidental security advantage through it’s 128-bit address space, scanning all of those addresses -even just for a single port- would take a fundamental shift in how IP scanning is performed to become feasible.
Building on top of this, because the IPv6 address space is so large, it is actually reasonable to just pick a random address and use it without conflict. In fact, this is so large that security benefits can be derived from it. For example, it is actually possible to use PKI cryptographic material in the generation of derived self-proving IPv6 addresses, meaning that route poisoning and the like could be prevented using cryptographic rather than trust-based means (Drake, 2016)
The key risks that we will face in moving to IPv6 are in the support for legacy hardware and software. While most modern devices will support IPv6 with little to no modification. All business have some legacy systems that will need to either be replaced, or positioned behind a IPv6-IPv4 NAT for compatibility purposes.
In addition, there will be significant training and user education required; network security control systems will need to be carefully tweaked so that they provide the same level of protection that is currently offered by existing systems, and technicians will need to be trained on how functions like ACL rule changes differ in IPv6. Many business power users are familiar with IPv4 even if they do not hold the title of network engineer, those users will need to re-learn the tricks that they employ to make our business run smoother.
