Group of answer choices

The two correct statements about IPv6 prefixes are:

  1. FF00::/8 is used for IPv6 multicast. - This is true, as the FF00::/8 prefix is designated for multicast addresses in IPv6.

  2. FE80::/10 is used for link-local unicast. - This is also true, correct prefix for link-local addresses in IPv6 ranges from FE80:: to FEBF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF.

The other two statements are not correct:

  • FEC0::/10 is used for IPv6 broadcast. - This is false because IPv6 does not use broadcast addressing; it uses multicast and other means for similar functionality.

  • FE80::/8 is used for link-local unicast. - This is false because the correct prefix for link-local addresses is FE80::/10.

So the true statements are the first and the fourth: FF00::/8 is used for IPv6 multicast and FE80::/10 is used for link-local unicast.
