Planks in IPV4:
• Problematic address format.
• Highly incompatible.
• Less mobility.
• Inconsistent header format.
• Inefficient routing.
• DHCP was required.
Catalog of features in IPV6:
• Expanded addressing capabilities.
• Header format simplifications.
• Improved support for extensions and options.
• Flow labeling capability.
• Authentication and privacy capabilities.
• Better multicast routing.
• Easier administration.
Why is IPV6 taken into action?
IPV6 is the latest level of internet protocol. It is termed as the “next generation” internet standard due to its highly efficient technology. There are plenty of transitions that have taken place in IPV4 to IPV6. The address format of IPV6 has now strengthened to 128 bits later it was 32 bits in IPV4. The networking basics of both the protocols are similar. There are some set of specifications that differ. To correct the shortcomings in IPV4 auto-configuration is supported. Now the new version is designed to solve many of the shortcomings of IPV4, including mobility and overall extensibility. These protocols provide IP addresses that will help identify the devices over the internet through their phone numbers.
Equipment, software or services needed for IPV6:
• Operating systems such as Mac OS X, Windows, and Android.
• Home security systems that use IP networks.
• Web browsing software such as Firefox or Internet Explorer.
• Computer Security software such as anti-virus programs and firewall.
As all the devices whether a small phone or a computer, if have access to an internet connection then they will obtain an IP address. They addresses of IPV4 were running out of the system due to the huge increase in the use of internet worldwide. Therefore, Internet protocol version 6 was introduced. We cannot say that IPV4 has vanished completely or should be vanished but as new devices are being used the addresses of IPV4 are obsolete. By and by, gradually the version 4 will vanish due to its constraints.
