Explain the significance IPV6 over IPV4.

The maximum size of an Ipv6 datagram is 65575 bytes, with the 0 bytes Ipv6 header. Ipv6 also describe a minimum reassembly buffer size: the minimum datagram size which we are guaranteed any implementation should support. The minimum size for Ipv6 datagram is 1500 bytes.

Even with retaining the fundamental concepts from IPv4, IPv6 modifies all the details. IPv6 utilizes larger addresses and a completely new datagram format. IPv6 utilizes a series of fixed-length headers to handle header information. Therefore, unlike IPv4, that places key information in fixed fields of the header and only appends variable-length options for less significant information, the IPv6 header is all the time variable size.
