(p.727) The IPv4 address pool officially ran out on January 31, 2011. Although no one can provide an exact date when the world will officially run out of IPv4 addresses, it is inevitable, and it is close . (ip4depletion) With the world now migrating from IPv4 to IPv6, now is the best time to start migrating Sample Company to IPv6. Understanding the differences between IPv4 and IPv6 is important as well as the hardware/software requirements needed for this migration. Migration has many benefits and many risks if Sample Company decides not to migrate. Let's get started.IPv4IPv4 uses a 32-bit address system which will give you a total of around 4.3 billion addresses. While this may seem like a lot of addresses, given the number of devices connected to the network today, these addresses are already exhausted. Some of the features that harm IPv4 include: • Networks must be configured manually or with DHCP. • The widespread use of NAT devices means that a single NAT address can hide thousands of non-routable addresses, making end-to-end integrity unachievable. • 4.2 billion addresses provide far less than a single IP address per person on the planet. • Internet Group Management Protocol (IGMP) manages the local subnet. • Supports a packet size of 576 bytes which can be fragmented. (Microsoft, 2009)IPv6The significant difference between IPv4 and IPv6 is that IPv6 has much more address space. IPv6 uses a 128-bit addressing system that provides approximately 340 undecillion (3.4 × 1038) available addresses. Although the addresses appear different,... middle of paper ...... reduce downtime for Sample Company while the upgrade is in progress. Bottom Line Crystal Bedell says: “Businesses that delay their IPv6 migration plans are putting themselves at risk. In the short term, you run the risk of no longer being able to communicate with customers. (2014) The bottom line is that IPv4 no longer has an IP address, migration to IPv6 is inevitable. Very soon, websites that haven't made the change will be inaccessible and existing IPv4 networks will perform so poorly that they won't last. Now is the time to act, by migrating Sample Company's infrastructure from IPv4 to IPv6. So we need to incorporate this effort into our budget and schedules as soon as possible. Many vendors have already developed IPv6 compatible solutions, so it will be very important to involve them in the planning process. IPv6 can also put strain on older hardware, so we need to plan the move carefully..
