Which IPv6 address block forwards packets to a multicast address rather than a unicast address?
Which IPv6 address block forwards packets to a multicast address rather than a unicast address?
In IPv6, the address block FF00::/12 is reserved for multicast addresses. Multicast addresses are used to forward packets to multiple destinations simultaneously, unlike unicast addresses which are used for one-to-one communication. This block of addresses allows efficient network routing to multiple receivers.
FF <- easiest way to remember multicast.
'FF <- easiest way to remember multicast.' i'm putting this on a shirt
Multicast: FF00/8 -- FF00:: - FFFF:: Global Unicast: 2000::/3, 2001::/3, 2002::/4, 2001:db8::/32 Link Local Unicast: FE80::/10 -- FE80:: - FEBF:: Unique Local Unicast: FC00::/7 -- FC00:: - FDFF:: Loopback: ::1/128 Correct Answer: C
Sorry I mean Correct Answer: D
A) Global Unicast B) Unique Local Unicast C) Link Local Unicast D) Multicast
The answer should be changed to FF00::/8. FF00 is correct.
I understand Timothyng's confusion but on the exam I took, it had a /12 mask as is shown here on examtopics.
so which is the correct ans?
D is correct
D is correct. Don't get thrown off by the /12 prefix, that's FF00-FF0F, which are valid multicast addresses.

All nice, but we want visual feedback
Bel nome😂😂
In IPv6, multicast addresses are used to send a single packet to multiple hosts simultaneously. The IPv6 address block that forwards packets to a multicast address rather than a unicast address is the FF00::/8 address block. Therefore, the correct answer is option D.
The IANA have reserved all IPv6 multicast addresses with a prefix of FF00::/8. Within this range, FF02::/16 is reserved for local-scope multicast addresses. The “FF” defines the destination as a multicast, the ‘0’ is within the organisation, and the final ‘2’ defines the multicast as having a scope of Link-Local.
D. FF00::/12 - This block of IPv6 addresses is reserved for multicast, meaning that addresses within this range are used to send packets to multiple recipients simultaneously.
