The depletion of IPv4 addresses is a reality and now appears within the traditional five year planning cycles for most organizations. Will you be ready when there are no more IPv4 addresses?

Assessment
A critical component of insuring IPv6 integration success is the understanding of the impact of the introduction of IPv6 on the current network infrastructure and applications.

• Are the applications coded properly to perform utilizing an IPv6 address?
• Do the current applications have IPv4 addresses embedded in them and what is the impact of the application not performing properly?

There are many differences between IPv4 and IPv6 such as IPv6 has a significantly simpler header format, which should enable faster aggregate throughput within the network – especially important in the network core. Using extension headers for “unusual”, or “special handling required” packets, rather than a monolithic options field, is also efficient. For example, considering how hard network engineers work to keep fragmentation levels low, having every IPv4 header carry 32 bits of zeros – for each unfragmented packet – seems particularly inefficient. Still, the IPv6 base header is 40 octets long, where the IPv4 header – with no options – is only 20 octets – this is simply a result of the use of 128-bit addresses.

Understanding the similarities and differences with IPv4 and IPv6 and then assessing your current applications for their impact on performance are critical to ensuring that the applications will perform as expected once a dual stack or IPv6 address is implemented into the network. Each and every application must be reviewed to determine utilization of IP addressing within the application itself. BrainTrust Ltd., combines the experience, technical knowledge and application understanding to assess your applications and modify any code appropriately to continue the applications performance.
