As one could infer, IPv6 is an improved version of the IPv4 protocol. IP or Internet Protocol is a protocol that is used to identify devices across the internet so they can be located (Fruhlinger, 2020). IPv6 is more advanced than IPv4 because of the following reasons:

• It has more efficient routing without fragmenting packets
• Eliminates the usage of NAT in order to extend the address space from 32 bits to 128 bits
• Has built-in network layer security
• Stateless address auto-configuration
• Improved header structure with less processing overhead
• Built-in Quality-of-Service (QoS) that distinguishes delay-sensitive packets (Juniper)

There are many reasons that the adoption of IPv6 has been slow in the public and private sectors. Two reasons why the adoption of IPv6 has been slow can account for the prices of IPv4 technology and NAT. The Internet Society that prices of IPv4 technology has peaked in 2018, and will drop when adoption rates of IPv6 technology reach 50% worldwide. NAT takes private IP addresses and turns them into public IP addresses. It allows organizations with a private IP address to send and receive packets from outside the private network. Without NAT, these organizations would have to use large quantities of IPv4 addresses to properly function (Fruhlinger, 2020)
