Currently, there are two versions of the IPs that are in utilization globally namely the IPv4 and IPv6. The two protocols differ in various ways. The IPv4 version incorporates a 32 bits version that varies to the IPv6’s which limits the address space to 232 equivalent to 4 294 967 296 distinctive addresses. The version also reserves some space for special addresses including the multicast and private addresses (Beijnum 2006, p. 117). The IPv6 has a size of 128 bits (16 octets) hence sufficient to incorporate huge blocks of address space as it provides probable unique addresses of up to a maximum of 2128 equivalent to 3.403 ×1038&nbsp.unique addresses. Therefore, IPv6 provides a larger address space to host much more blocks in comparison to the IPv4 version (Savolainen, Korhonen & Soininen 2013, p.57).

In the contemporary world, the internet has become an essential part of an individual’s life. Therefore, improving the existing network is crucial to ensure higher performance and reliability in the current generation. Generally, the internet utilizes IP protocol technology known as the IPv4. Even though the IPv4 has been an essential element of modern technology, it is inadequate to hold a much higher range of addresses. It initially allowed over 4 billion addresses from different host devices, and the number of addresses being added to the protocol is now finite and telecommunication companies have identified the next generation solution. The answer to network traffic is IPv6, which provides more addresses. Consequently, the transition to IPv6 is quite challenging, as the two are not compatible and hence a number of transition strategies have been addressed to ensure users are transforming to IPv6.
