A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00:: / 7. [1] These addresses are non-globally reachable [2] (routable only within the scope of private networks, but not the global IPv6 Internet).
IPv6 multicast addressing has features and protocols in common with IPv4 multicast, but also provides changes and improvements by eliminating the need for certain protocols. IPv6 does not implement traditional IP broadcast, i.e. the transmission of a packet to all hosts on the attached link using a special broadcast address, and therefore does ...
EE enabled IPv6 on the Radio access network for most consumers by Autumn 2018. Their home broadband services currently do not support IPv6 however. [264] Aquiss enabled IPv6 for their broadband customers in 2015. In February 2020 they completed their IPv6 rollout for services and systems i.e. web hosting platform, VOIP and other services. [265]
If the upper-layer protocol is unable to do so, the sending host may use the Fragment extension header instead. Any data link layer conveying IPv6 data must be capable of transmitting an IP packet containing up to 1,280 bytes, thus the sending endpoint may limit its packets to 1,280 bytes and avoid any need for fragmentation or Path MTU Discovery.
IPv6 hosts may automatically generate IP addresses internally using stateless address autoconfiguration (SLAAC), or they may be assigned configuration data with DHCPv6, or both. IPv6 hosts that use stateless autoconfiguration may need information other than what SLAAC provides on a given network.
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]
An Internet Protocol version 6 address (IPv6 address) is a numeric label that is used to identify and locate a network interface of a computer or a network node participating in a computer network using IPv6. IP addresses are included in the packet header to indicate the source and the destination of each packet.
The successor to IPv4 is IPv6. IPv6 was a result of several years of experimentation and dialog during which various protocol models were proposed, such as TP/IX (RFC 1475), PIP (RFC 1621) and TUBA (TCP and UDP with Bigger Addresses, RFC 1347). Its most prominent difference from version 4 is the size of the addresses.
