Several examples of IPv6 extension headers. The IPv6 packet header has a minimum size of 40 octets (320 bits). Options are implemented as extensions. This provides the opportunity to extend the protocol in the future without affecting the core packet structure. [2]

Windows 11 Yes 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 ...
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.
Windows 10 Creators Update introduces support for RFC 8106 (6106) RDNSS. Windows Mobile: 6.5: Yes Yes Lite [33] No If the OEM explicitly unsets the SYSGEN_TCPIP6 pre-processor symbol, the built image will not have any IPv6 capabilities. Windows Phone: 7.5 No No No No 8 [34] Yes Yes Yes No Private lab research. No privacy extensions (RFC4941). z ...
For such use cases, a special notation has been introduced, which expresses IPv4-mapped and IPv4-compatible IPv6 addresses by writing the least-significant 32 bits of an address in the familiar IPv4 dot-decimal notation, whereas the 96 most-significant bits are written in IPv6 format. For example, the IPv4-mapped IPv6 address ::ffff:c000:0280 ...
IPv6 is the successor to IPv4 and has a different header layout. It was defined in 1998 and is in various stages of production deployment . The header in IPv6 packets is subdivided into a mandatory fixed header and optional extension headers.
IPv6 uses the Neighbor Discovery Protocol and its extensions such as Secure Neighbor Discovery, rather than ARP. Computers can maintain lists of known addresses, rather than using an active protocol. In this model, each computer maintains a database of the mapping of Layer 3 addresses (e.g., IP addresses ) to Layer 2 addresses (e.g., Ethernet ...
