The replacement of IPv4 by IPv6 will oversee multiple features in networks operating under the TCP.IP protocol. These new features clearly indicate the advantages of the new communication protocol. It is pertinent to note that these new features are aimed at enhancing the quality of service of data networks. The most visible benefit of the IPv6 is the number of unique permutations that can be used to identify devices. The IP addresses available for use under IPv6 will be much more than those available under the IPv4.
The new communication protocol will also be characterized by different header formats. These formats will be instrumental in enhancing the efficiency of addressing as well as routing schemes. The header format also ensures that a hierarchical addressing is achieved. Another feature of IPv6 is its support of both the stateful and stateless address configuration. This is instrumental in simplification of IP address configuration across a network with many hosts. A stateless address allows automatic configurations.
Another pertinent feature of the communication protocol is the built-in security abilities. The IPv6 supports IPSec which is part of its requirement for proper operation. This is instrumental in laying a foundation for network security within a network. The extensibility capabilities of IPv6 allow for inclusion a header that is variable in size. The IPv6 adopts 128 bits that can accommodate 3.4*1038 unique addresses (Mun, & Hyewon 56).
The IPv6 will speed up the processing of TCP/IP packets since headers used in addressing will be clearly labeled. Moreover, it support of hierarchical addressing allows for the use of smaller routing tables in network equipments. This significantly reduces the processing speed of these devices. The routing infrastructure in a TCP/IP network will apply fewer levels as compared to IPv4.
