4. At one time, it was believed that the world would soon run out of IP addresses. Accordingly, a new protocol called IPv6 was proposed with longer IP addresses that provide many more unique IP addresses. During that same time, however, DHCP and NAT began to see widespread use, and their use dramatically reduced the growth in need for unique IP addresses. Explain why this is so. Suppose you are the director of product planning for a high-tech company and 5 years ago you had been the initiator and principal proponent for the development of a new line of products based on IPvé6. Your product sales have been substantially below your estimates.

What do you do now? What product development principle(s) can you extract from this situation? How can you protect your organization from such situations in the future?
