    Hi Jeevan,

    Nice question. As you know today we are using IPv4. IPv6 is the future IP addressing format. IPv4 is 4th Version of Internet Protocol and IPv6 depicts 6th version of internet protocol. Format of IPv4 is and IPv6 is, To communicate over internet, we require independent IP addresses. Now internet users are increasing drastically So IPv4 is not enough to provide IPs to all.

    To overcome these issues, IPv6 developed.

    To get more details about IPv6, see IPv6

    Jeevan Sir,

    There are some basic difference between an IPv4 and IPv6. Here it is:

    - IPv4 are manually worked and with DHCP as an additional options. IPv6 can be handled automatically and does not require manual automation or with DHCP.

    - IPv4 have address which are 32 bits in length whereas in IPv6, the addresses are 128 bits in length.

    - If IPSec is there which is additional, then it should be supported externally. In case of IPv6, the IPSec requirement in not optional.

    - ARP manually uses ARP Broadcasting to resolve Internet Protocol to MAC/Hardware addresses. In IPv6, Multicast Neighbor Solicitation messages resolve IP addresses to MAC addresses.

    - Header option includes a checksum in IPv4 and incase of IPv6, there are no options included for checksum monitoring. This makes the sources more reliable.

    - Ipv4 must have a recommended 576 byte packet size whereas in IPv6, it must get a support of 1280 size packet size monitoring. This helps in making a tough support to computing solutions.
