The Internet is migrating from IPv4 (Internet Protocol version 4) to IPv6 (Internet Protocol version 6). The high cost of migration services from IPv4-IPv6 and system complexity are main factors for slow adaption of IPv6 This paper presents the implementation of migration techniques from IPv4-IPv6. Furthermore, existing IPv4 addresses have already been depleted in IANA (Internet Assigned Numbers Authority) and will be soon exhausted in RIR (Regional Internet Registry) while more clients are joining the Internet. Slower rate of the progress of IPv6 confirms complete shifting from IPv4-IPv6 at once is still long away, although fewer parts of IPv6 have been employed in current market goods. Integration of IPv4 and IPv6 is carried in order to take care of online users. In this paper, it is suggested that hierarchical direction finding structural design in IPv4 and IPv6 will improve the efficiency of IPv4 network. This research work provides the way to design the network scenario for the carrier grade set of connections. The carrier grade network scenario routers are named to be Karachi, Sukkur, Islamabad, Multan and Peshawar for the managerial simulation purposes. The carrier grade network deployment is implemented along with dual stack to migrate to IPv6. This study holds the way to deploy IPv4-IPv6 carrier grade network by providing real time scenario which is yet not considered in the literature to the best of our knowledge
