The primary protocol that enables communication between computers is called IP (Internet Protocol): Each device connected to the internet has a unique numeric address known as an IP address used to route information from the sender to the receiver. The current version of IP (IPv4) enables the allocation of IP addresses to approximately 4.3 billion devices connected to the internet. However, the number of connected devices already exceeds the number of available IPv4 addresses, and the ubiquity of IoT (Internet of Things) will create an even greater shortage of IPv4-based IP addresses. Since temporary solutions, such as local networks, can’t match long-term demand and create new problems, the world currently transitions to a new protocol – IPv6 – which supports 340 trillion trillion trillion (3.4×1038) individual IP addresses, resolves the address shortage and fixes other problems. This paper highlights the immediate need to transition to the new protocol, provides information on different protocols and interim mechanisms, and outlines fundamental obstacles of implementing IPv6. The Ministry of Communications adopted the recommendations presented in the paper as the foundation for future nationwide action.
