The internet, the number of internet users, the volume of mobile devices, and the number of constantly connected devices have been growing at a tremendous rate, the growth is far beyond the original growth expectations for which the network is designed. The continued adoption of mobile broadband and increase in the number of internet users, as well as the amount of devices per user, are hastening the exhaustion of internet Protocol version 4 (IPv4) addresses. The internet Protocol version 6 (IPv6) was designed to use a much larger address space, in addition to providing other benefits. These benefits include simpler packet forwarding in routers, increased security and auto-configuration. The financial and business impact of address exhaustion will affect telecom operators and service providers.
The current version of the internet protocol (is based on 32-bit addresses that allow unique identification for a maximum of 4 billion nodes. Based on current projections, the free pool of network addresses will be exhausted very soon. The absence of available IPv4 addresses will prevent subscriber growth and will become a threat to business continuity. In short, migration to IPv6 is vital.
