A comparative review of IPv4 and IPv6 for research test bed

The Internet is migrating from IPv4 to IPv6. To determine the features for research test bed product selection, we compare the up-to-date information of IPv4 and IPv6. Currently IPv6 network penetration is still low but it is expected to grow, while IPv4 address pool is projected by Regional Internet Registry to be exhausted by the end of 2011. The reason why uptake of IPv6 is still low is because of high cost of service migration from IPv4 to IPv6, successfully used of IPv4 Network Address Translation for Intranet and unproven return of investment in IPv6 technology. This paper aims to review few migration path from IPv4 to IPv6 and some of the existing IPv6 products.
