A PC has only an IPv6 address that begins with fe80, and it cannot reach the internet. Other PCs with routable addresses can. Which limitation is that?
Select an answer to reveal the explanation.
Short Explanation
The address is a front-door number that only works inside the building, and the internet will not carry it. You need a routable address. Calling this prefix public, confusing it with the IPv4 fallback range, or publishing a mail record does not give the PC a path out.
Full Explanation
IPv6 addresses that begin with fe80 are link-local. They are used on the local link and are not routed onto the internet. This PC has only that address, which is why it cannot leave the link while other PCs with routable addresses can. An fe80 address is not a public internet address. IPv4 automatic private addressing uses 169.254.0.0/16, not an fe80 prefix. An MX record names a mail host. It does not route an IPv6 workstation onto the internet. Exam caveat: a host can have a link-local address and a routable address at the same time. The problem here is that the routable one is missing. Operational check: assign or obtain a routable IPv6 address, confirm fe80 is no longer the only address, and ping a host beyond the router. Obtain a routable address and confirm fe80 is no longer the only address on the PC. Note the result on the ticket. Ping past the router only after a routable address is present.
