What Is the Primary Reason Ipv6 Has Not Completely Replaced Ipv4?

NAT network address translation and (CIDR) classless Inter-Domain routing reduce the need for registered IPv4 addresses This is the main reason why IPv6 does not completely replace IPv4.

IPv4:

Internet protocol version 3 is a set that permits the devices to interchange the data on the internet such as phones, to computers. So, by a specific number every domain and device are connected to the internet is called an IP address. The purpose of the internet protocol is to ensure that data is transferred to the correct device. DNS domain name system is like the internet book. This translates the domain name to IP address. For example, when you type Netflix in your PC browser this internet phone book is permitted to be in touch with Netflix IP address. Once it translates Netflix sends its contents to your PC internet protocol address. Internet protocol version 4 is a 32-bit number written as four decimal points. The number between each decimal is 0 and 255.

IPv4 is not enough because 32-bits it restricts the number of hosts. It means with 32-bits 4.3 billion IPv4 addresses are accessible. A large number of devices are connected to the internet (IETF) internet engineering tracking task force designed a new protocol called internet protocol version 6. IPv6 is faster and connected a greater number of devices but still, IPv4 is used because IPv6 is new not all the devices are setup to communicate with IPv6 so most of the internet traffic used IPv4. It is highly demanded in business.

IPv6:

Internet protocol version 6 contains bits length 128 and comprises 16- bits field each field is a sphere by a colon. It contains hexadecimal number while IPv4 contain dotted-decimal notation.

Benefits of IPv6:

These are some benefits IPV6 used over IPv4:

• No need for private address collision
• Simple format
• No need for network address translation
• Auto configuration
• Multicast routing is best
• Greater efficient routing
• It supports privacy and authentication
• Good quality of service
• It is more compatible with the network than IPv4
• It permits a greater payload
• It used less than 1% network while the remaining 99% was used by the IPv4.
• Its speed is higher than IPv4.
