Which of the following is true about link-local addresses in IPv6?

Link-local addresses in IPv6 are designed specifically for communication within a local network segment or link. They are typically generated automatically and do not require any manual configuration. This automatic assignment occurs during the IPv6 address autoconfiguration process, where an interface can generate its own link-local address using its MAC address (through a process known as Modified EUI-64) or by choosing a random address in the required range.

The range for link-local addresses is defined within the FE80::/10 subnet, meaning any address that begins with FE80 and is followed by zeros can be recognized as a link-local address. These addresses play a crucial role in neighbor discovery protocols and local communication without needing a router.

In contrast, link-local addresses are not routable over the internet, nor are they globally unique, and they do not require manual configuration. Their primary purpose is to facilitate local communication within a network segment.
