Chapter 10: IPv6
What protocol does IPv4 use to resolve the IPv4 address to the MAC address?
ARP
What was the original reason for developing IPv6?
running out of IPv4 addresses was imminent

This mechanism provides a means of communication across the IPv4 Internet and preserves the original IPv6 address of the device.
6to4
How are the 128 bits divided?
8 sets of 16 bits
The 24-bit manufacturer's ID and the 40-bit unique ID make up the last 64 bits of an IPv6 address. What is this known as?
EUI-64 Identifier
What protocol is designed to exchange messages between neighboring nodes on the same link?
ICMPv6
What protocol does IPv6 utilize that helps provide better security than IPv4?
IPSec
What are the two types of IP addressing schemes called?
IPv4 and IPv6
Which type of IP address allows for faster delivery of information?
IPv6
What does ICMPv6 stand for?
Internet Control Message Protocol Version 6
What are the two flags set on the computer to determine what that computer will get from the DHCP server?
M Flag and the O flag
Which flag determines if the address will be static or dynamic?
M flag
THe EUI-64 identifier serves the same function as the IPv4 ___ ____.
MAC address
Which flag determines if a computer will get other data from the DHCP server?
O flag
What addressing is used for topology discovery, gateway discovery, and group discovery?
Multicast address
What protocol does IPv6 use to resolve the IPv6 address to the MAC address?
Neighbor Discovery
What commands displays current TCP/IP and port statistics?
Netstat
What allows for automatic configuration of network devices and the discovery of router devices attached to the local area network?
Network discovery
Which lifetime is typically a day?
Preferred lifetime
What is defined as a protocol's ability to deliver certain packets in a timely fashion?
Quality of service
What IDs are used for local-use address to indicate which zone on a local area network a site-local address is used?
Zone IDs
What classification of address delivers packets to the nearest interface and is used mainly for supporting router functions?
anycast address
Name two of the advantages of IPv6.
better network traffic and better security
What type of address sends packets to all network addresses?
broadcast address
What is another name for IPv6?
classless IP addressing scheme
What layer of the OSI model does ND protocol reside?
data link layer
What is the public address used to identify the local network?
global address
What type of address can broadcast to all IPv6 addresses in the IPv6 portion of the local area network as well as to other global IPv6 addresses in the entire network as well as the LAN?
global unicast address
What are the three terms used to describe the scope of the network?
global, link local, and unique local
Why is IPv6 known as that?
it is not broken into classes (A, B, and C) like IPv4 is
What is a portion of the organization's network called that is broken into subnetworks?
link-local
What type of addresses are automatically assigned by the operating system and are required for the network discovery feature?
link-local unicast address
What type of addresses are used to communicate on the local area network and will not be forwarded by the router?
link-local unicast address
What type of address is the reserved IP address of the network interface card?
loopback address
What classification of address delivers packets to multiple addresses?
multicast address
What type of address sends packets to a specific set of addresses?
multicast address
Which command is used to send a packet from one host to another on a network and then echo a return reply?
ping
What is the portion of the address with a fixed value that informs network devices of what action to take?
prefix
What is the purpose of the ND protocol?
to discover neighboring devices automatically
What is IPSEC used for?
to encrypt and authenticate every packet sent
What are the three types of classifications for IPv6?
unicast ,multicast, and anycast
What classification of address delivers packets to a single network address?
unicast address
What type of address serves the same function as a site-local address and can represent an entire LAN or just a portion?
unicast address
In what type of network can a router forward packets to any portion of the organization's network but not outside the organization's network?
unique-local
What is the entire organization's network or a portion of it called?
unique-local
What type of address is used when the interface is checking for its own duplicate address during the initial connection to the network?
unspecified address
Which lifetime is typically a week?
valid lifetime
IPv6 has two lifetime values, what are they called?
valid lifetime and preferred lifetime
