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. Don't get thrown off by the /12 prefix, that's FF00-FF0F, which are valid multicast addresses.
D is correct
All nice, but we want visual feedback
Bel nome😂😂

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.
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.
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.
