Question

A server needs to connect directly to the Internet. The ipconfig/all command shows that the server has been auto-assigned the IPv6 address fe80::260:8ff:fec0:98d%4. It won’t connect to the Internet because it is a _________ address, which does not have Internet access

Answer 1

Answer:

Link-local address

Explanation:

IP addresses that have "FE80" as the hexadecimal representation of their first 10 bits are IPV6 reserved addresses for link-local unicast addressing. These addresses are automatically configured (though may be manually configured too) on any interface and should not be routed. They are used for addressing on a single link with the main aim, among others, of automatic configuration and routing protocol advertisement. Devices attached to this link can be accessed or reached using the link-local addresses as they don't need a global address to communicate.

However, routers will not forward datagram or packets using link-local addresses. In other words, routers are not allowed to connect to the internet using the unicast link-local addresses.
