1) in Ipv6, the Anycast Feature Allows

1) In IPv6, the anycast feature allows - a) senders to address packets to all nodes in a group b) senders to address to packets to any member of a group of nodes c) receivers to listen for any given packet on the network d) receivers to announce their presence to potential senders

2) IPv6 addresses are divided into 3 main components. Which component describes the phone company you receive internet connectivity from?

3) How can a sender determine if a receiver can receive an IPv6 packet?

4) Suppose one IPv6 router wants to successfully send a packet to another IPv6 router, but the two are connected together only via an intervening IPv4 router. If the two routers use tunneling, then: a. the sending IPv6 router creates an IPv4 packet and puts it in the data field of an IPv6 packet. b. the sending IPv6 router creates one or more IPv6 fragments, none of which is larger than the maximum size of an IPv4 packet. c. the sending IPv6 router creates an IPv6 packet and puts it in the data field of an IPv4 packet. d. the sending IPv6 router creates an IPv6 packet and intervening IPv4 router will reject the IPv6 packet

5) Which has a smaller header when measured in byte, IPv4 or IPv6?

6) (True/False) Every IPv4 address has a unique mapping to an IPv6 address. In other words, for every IPv4 address, we know how to make the corresponding IPv6 address.

7) (True/False) Every IPv6 address has a unique mapping to an IPv4 address. In other words, for every IPv6 address, we know how to make the corresponding IPv4 address.

8) What field in the IPv6 header has the same functionality as the IPv4 header’s Protocol field?

9) What field in an IPv6 header has the same functionality as the IPv4 header’s header length field?

10) What field in an IPv6 header has the same functionality as the IPv4 header’s Type of Service field? 11) How many bytes are in the IPv6 address 0::1?

12) The IPv6 multicast feature might reasonably by used for (pick one) DNS Internet Radio SSH Sending queries to www.google.com

13) (True/False) IPv4 applications need to be modified and recompiled to use IPv6?

14) (True/False) There are more than one million possible IPv6 numbers per person on the entire globe including children.

15) Who fragments a packet in IPv6? Sender Intermediate routers as needed Receiver Fragmenting has been eliminated from IPv6

16) How many headers are needed to send a standard IPv6 TCP packet? What are they?
