10 things you should know about IPv6 addressing - TechRepublic
The IPv6 protocol for Windows Server 2008 and Windows Vista sends the Router Solicitation message before performing duplicate address detection on the link-local address. In this way, duplicate address detection and router discovery are done in parallel to save time during the interface initialization process. For IPv6 link-local addresses (fe80::/10 prefix), the sin6_scope_id member in the sockaddr_in6 structure is the interface number. For IPv6 site-local addresses (fec0::/10 prefix), the sin6_scope_id member in the sockaddr_in6 structure is a site identifier. An example of a link-local IPv6 address on interface #5 is the following: Example 3-1 Parts of the Link-Local Unicast Address. A link-local prefix has the following format: fe80::interface-ID/10. The following is an example of a link-local address: fe80::23a1:b152. fe80. Hexadecimal representation of the 10-bit binary prefix 1111111010. This prefix identifies the type of IPv6 address as link local. interface-ID Local IPv6 Address Generator. Local IPv6 Address Generator tool generates a Local IPv6 Address by getting Global ID and Subnet ID as input and ouputs the various parameters required for an IPv6 Address. This tool proves helpful when using IPv6 on your local computer. The link-local address of a node is the combination of the prefix fe80::/64 and the 64-bit interface identifier expressed in IPv6 colon-hexadecimal notation. Therefore, the link-local address of this example node with the prefix fe80::/64 and the interface identifier 02-60-08-ff-fe-52-f9-d8 is fe80::260:8ff:fe52:f9d8. Aug 07, 2013 · With IPv6 we can simplify this statement further and use a link-local address as the default gateway. 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 Instead of getting an address via DHCP, a NIC will hop on the network with a link-local IPv6 address and with this will have to ability to do further configuration automatically (soliciting neighbors, router, et cetera). This link-local IPv6 is infered from the NIC’s mac address. A mac address is 48 bits, an IPv6 address is 128 bits.

Every IPv6 interface is going to get a Link-Local address so that a device can at least communicate on the local link, and, as a built-in feature, many things, e.g. routing protocols, use it for communications on the local link.
Ipv6 link-local - Cisco Community > 5) Also I noticed link-local address doesnt have any subnet like /64, /127,etc. Does it means it is /128? The link-local addresses are defined by RFC4291 and have a fix format, hence we do not need to configure the prefix length. 2.5.6. Link-Local IPv6 Unicast Addresses. Link-Local addresses are for use on a single link.
