The payload of an IPv6 packet is typically a datagram or segment of the higher-level transport layer protocol, but may be data for an internet layer (e.g., ICMPv6) or link layer (e.g., OSPF) instead. IPv6 packets are typically transmitted over the link layer (i.e., over Ethernet or Wi-Fi), which encapsulates each packet in a frame.
ISATAP typically builds its Potential Router List (PRL) by consulting the DNS; hence, in the OSI model it is a lower-layer protocol that relies on a higher layer. A circularity is avoided by relying on an IPv4 DNS server, which does not rely on IPv6 routing being established; however, some network specialists claim that these violations lead to insufficient protocol robustness.
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.
The Link-Local Multicast Name Resolution (LLMNR) is a protocol based on the Domain Name System (DNS) packet format that allows both IPv4 and IPv6 hosts to perform name resolution for hosts on the same local link.
An IPv6 transition mechanism is a technology that facilitates the transitioning of the Internet from the Internet Protocol version 4 (IPv4) infrastructure in use since 1983 to the successor addressing and routing system of Internet Protocol Version 6 (IPv6). As IPv4 and IPv6 networks are not directly interoperable, transition technologies are ...
Mageia has had full support for IPv6 only and IPv4 + IPv6 since Mageia 7, as well as continuing to support IPv4 only systems. [15] macOS: Mac OS X 10.7 (Lion) Yes Yes Yes [16] Yes [17] Versions 10.7 through 10.10 often prefer IPv4 even when working IPv6 connectivity is available. [18]
The Dynamic Host Configuration Protocol version 6 (DHCPv6) is a network protocol for configuring Internet Protocol version 6 (IPv6) hosts with IP addresses, IP prefixes, default route, local segment MTU, and other configuration data required to operate in an IPv6 network.
There is a difference between a "relay router" and a "border router" (also known as a "6to4 border router"). A 6to4 border router is an IPv6 router supporting a 6to4 pseudo-interface. It is normally the border router between an IPv6 site and a wide-area IPv4 network, where the IPv6 site uses 2002:: / 16 co-related to the IPv4 address used later ...
