ANSWER:
Classless Interdomain Routing (CIDR) allows IP addresses to be configured with subnet
masks regardless of the address class. CIDR provides flexibility in IP address assignment and
subnetting. From CIDR came CIDR notation where an IP address can be written as
address/prefix such as 192.168.10.5/26 where the /26 indicates the number of 1 bits in the
subnet mask.

NAT translates a private IP address to a public IP address and there is a one to one ratio of

45. List and describe three of the seven discussed improvements that IPv6 has over IPv4.
ANSWER:
Larger address space-IPv4 addresses are 32 bits, which provide a theoretical four
billion addresses. IPv6 addresses are 128 bits, so the number of possible addresses
can be expressed as 34 followed by 37 0s, or 340 trillion trillion trillion. Hierarchical
address space-Unlike IPv4, in which numbers in the address have little meaning other
than the address class, and the network ID and host ID, IPv6 addresses have a more
defined structure. Autoconfiguration-IPv6 can be self-configuring or autoconfigured
from a router or server running IPv6 or through DHCPv6. Built-in quality of service
(QoS) support-IPv6 includes built-in fields in packet headers to support QoS
strategies. Built-in support for security-From the ground up, IPv6 is built to support
secure protocols, such as Internet Protocol Security (IPsec). Support for mobility-
With built-in support for mobility, routing IPv6 packets generated by mobile devices
over the Internet is more efficient than with IPv4. Extensibility-IPv6 uses extension
headers instead of IPv4’s fixed-size 40-byte header.

46. How does the ARP protocol work? How can you display and delete the local ARP cache?
ANSWER:
When an IP packet is sent to a destination on the local network, the sending device must have
the destination’s MAC address. The source computer retrieves the MAC address by sending a
broadcast ARP request packet to the local network. The ARP request packet essentially asks
“Who has IP address A.B.C.D?” The computer on the local network that’s assigned the IP
address sends an ARP reply message containing its MAC address. You can display the ARP
cache with the command arp -a and you can delete it with arp -d.

47. How can an IPv6 interface ID be assigned to a host?
ANSWER:
An IPv6 interface ID can be assigned to a host in these ways: Using the 48-bit MAC
address-Because a MAC address is only 48 bits, the other 16 bits come from the
value fffe inserted after the first 24 bits of the MAC address. In addition, the first two
0s that compose most MAC addresses are replaced with 02. A randomly generated
permanent interface identifier-The interface ID is generated randomly but is a
permanent assignment maintained through system restarts.

Name:
Class:
Date:
ANSWER:
Anycast addressing is a cross between unicast and multicast. Multiple nodes are assigned the
same address, and packets sent to that address are delivered to the “closest” node. So
although packets sent with a multicast address are delivered to multiple destinations, the
anycast address is sent to only one of a group of nodes sharing the same anycast address.

50. How does a computer know when to send packets to the default gateway?
ANSWER:
The sending computer must first know its network address. It determines this by doing a
logical AND operation between its IP address and subnet mask, which results in the network
ID of the address. The next step is to determine whether the destination computer’s address is
on the same network or a different network. The same AND calculation is done between the
destination computer’s IP address and the sending computer’s subnet mask. The result is the
destination computer’s network ID. If the network ID of the sending computer is different
than the network ID of the destination, the packet is sent to the router or default gateway.
