CONCLUSION

IP address space is clearly one of the most critical resources that an Internet data center needs to manage. The fact that IP address space is a limited resource drives many technology and operational decisions. Even private address space, once thought to provide relief from addressing problems, can be the source of problems as two organizations find themselves trying to address private space address collisions. IPv6 holds some promise for relieving many of these problems, but the Internet has quite a ways to go before there is widespread adoption of IPv6.
