Internet Protocol Version 6 (IPv6) was designed to address the limitations of Version 4 (IPv4). What cybersecurity-related enhancements have been incorporated into IPv6? The adoption of IPv6 has been pretty slow across both the public and private sectors. What reasons can you attribute to this? Cite resources and references that support your assertions.
IPv6 was meant to address not only the security limitations, but the eventual hard cap of IP addresses that IPv4 would face in the future. IPv6 utilizes 128 bits, more than IPv4 which only uses 32 bits, making it more secure and ensuring that it is unique. IPv4 is vulnerable to DDOS attacks, as well as spoofing and potentially malware attacks as well while IPv6 is more secure from them.
IPv4 was predicted to have an address cap at just over 4 billion was predicted to run out of addresses in 2021, so IPv6 was developed and introduced, which had a cap of potentially over 340 trillion. While widely used in India currently, the overall adoption of IPv6 has been held off thanks to network address translation, which can translate a private IPv4 address to a public one, as well as the use of subnetting an IPv4 address to help address this issue. While IPv6 is more secure, offers better quality service, and a currently indefinite lifespan, IPv4 is so widely used currently that it will take time, and resources for people and organizations to make the move to utilizing IPv6 instead.
