IPv6-enabled network interfaces usually have more than one IPv6 address, for example, a link-local and a global address. They may also have temporary addresses that change after a certain lifetime has expired. IPv6 introduces the concepts of address scope and selection preference, yielding multiple choices for source and destination address

Interestingly, IPv6 Link Local Address has been actively utilized since its creation, its capabilities and functionality has only garnered attention throughout the last couple of years. Regardless of your interest or experience in computer networks and backend infrastructure, understanding the role and potential of this widely used network RFC 4291 IPv6 Addressing Architecture February 2006 Currently, IPv6 continues the IPv4 model in that a subnet prefix is associated with one link. Multiple subnet prefixes may be assigned to the same link. 2.2.Text Representation of Addresses There are three conventional forms for representing IPv6 addresses as text strings: 1. The preferred form is x:x:x:x:x:x:x:x, where the 'x's are one to In IPv6 Link-Local addresses are mandatory addresses according to RFC 4291. This means that all interfaces are required to have at least one Link-Local unicast address from the address block fe80::/10, which has been reserved for link-local unicast addressing. The actual link-local addresses are though assigned with the prefix fe80::/64. IPv6 address with % sign is called Link-Local IPv6 address.IPv6 addressing is done n this way. An address exists on every computer NIC that has network part same for all computers in the world.

Link-local addresses are used only in communication between nodes on the same local link. A link-local address uses a link-local prefix of FE80::/10 as the first 10 bits (1111111010 in binary) and an interface ID as the last 64 bits. When IPv6 runs on a node, a link-local address that consists of a fixed prefix and an interface ID in EUI-64

IPv6 Link Local addresses are used by devices for communicating with other nodes on the same link. The scope of an IPv6 Link Local address is the local link. IPv6 Link Local addresses are auto-generated and many international technology leaders generate IPv6 Link Local addresses from MAC Address of the interface. Like IPv6 link-local addresses, these APIPA addresses are usable addresses for unicast communications within a single broadcast domain on the LAN. Link-Local Address as Default Gateway. Link-local IPv6 addresses are on every interface of every IPv6-enabled host and router. They are essential for LAN-based Neighbor Discovery communication.

An IPv6 link-local address is an equivalent of IPv4's: APIPA addres. Which of the answers listed below refers to an IPv6 link-local address? FE80::/64 ( Your answer) Which of the following answers lists a valid address of FE80:00A7:0000:0000:02AA:0000:4C00:FE9A after compression?

Routing protocols in IPv6 use the link-local addresses of routers as next-hop addresses so again, the communication based on link-local addresses must actually be possible. However, when you have a look at an IPv6 routing table, a network together with a link-local next-hop address will always be identified together with the outgoing interface: Interestingly, IPv6 Link Local Address has been actively utilized since its creation, its capabilities and functionality has only garnered attention throughout the last couple of years.

An address exists on every computer NIC that has network part same for all computers in the world. Unique local IPv6 addresses begin with FD00::/8. A unique local IPv6 address is constructed by appending a randomly generated 40-bit hexadecimal string to the FD00::/8 prefix. The subnet field and interface ID are created in the same way as with global IPv6 addresses. A graphical representation of an unique local IPv6 address: Firs, link-local address is alway an IP address. Not always, most commonly people do mean a link-local IP addresses when they use the term. When they mean this the addresses are always IP addresses, either IPv4 or IPv6. It is valid in some circumstances to refer to a MAC address as a link-local address but it is a less common use of the term.
