IPv6 was designed as the successor protocol for IPv4 with an expanded addressing space. IPv4, which has been in use since 1982, is in the final stages of exhausting its unallocated address space, but still carries most Internet traffic. [1]
IPv4 address exhaustion is the depletion of the pool of unallocated IPv4 addresses.Because the original Internet architecture had fewer than 4.3 billion addresses available, depletion has been anticipated since the late 1980s when the Internet started experiencing dramatic growth.
Following World IPv6 Day in July 2011, there were reports of a substantial reduction in IPv6 brokenness as a result of that experiment. [7] In the year following the trial, but prior to the World IPv6 Launch date, brokenness levels were reported to have risen slowly back upwards again towards 0.03%.

The current use of the IPv6 Traffic Class field divides this between a 6 bit Differentiated Services Code Point [33] and a 2-bit Explicit Congestion Notification field. [34] Extension headers carry options that are used for special treatment of a packet in the network, e.g., for routing, fragmentation, and for security using the IPsec framework.
An IPv6 packet is the smallest message entity exchanged using Internet Protocol version 6 (IPv6). Packets consist of control information for addressing and routing and a payload of user data. The control information in IPv6 packets is subdivided into a mandatory fixed header and optional extension headers.
An example of the fragmentation of a protocol data unit in a given layer into smaller fragments. IP fragmentation is an Internet Protocol (IP) process that breaks packets into smaller pieces (fragments), so that the resulting pieces can pass through a link with a smaller maximum transmission unit (MTU) than the original packet size.
Supports IPv6 addresses under Windows using brackets as [IPv6]:port Windows File Explorer: Windows Tested with Windows 7–10, maybe XP: Yes Supports IPv6 addresses in the address field, using \\fe80--abcd-eff0.ipv6-literal.net using dashes instead of colons. Microsoft Exchange Server [1] Windows 2013+ Yes Internet Explorer [1] Windows 9+ Yes
