Review of Basic Questions Chapter 9
1. How many bits in MAC address? 48
2. How bits in IPv4 IP address? In IPv6 IP ? 32, 128
3. How does a client app identify a server app on another computer on the network? Transmission Control Protocol (TCP) & Internet Protocol (IP)
4. What are IP addresses called that begin with 10,172.161 or 192.168? Private IP addresses
5. In what class is the IP address 185.75.255.10 ? Class B
6. In what class is the IP address 193.200.30.5? Class C
7. Describe the difference between public and private IP addresses. If a network is using private IP addresses, how can the computers on that network access the internet? Public IP addresses are available for use on the Internet & private IP addresses are not allowed on the Internet. Private IP addresses can still access the internet if a writer or other device that stands between the network and Internet is using NAT (Network Address Translation).
8. Why is it unlikely that you will find the IP address 192.168.250.10 on the internet? This is a private IP address not available on the network.
9. If no DHCP server is available when a computer configured for dynamic IP addressing connects to the network, what type of IP address is assigned to the computer? Automatic Private IP Address (APIPA)
10. If a computer is found that have an IP address of 169.254.1.1, what can you assume about how it received that IP address? It was unable to lease an IP address from the DHCP server
11. What are the last 64 bits of a IPv6 IP address called? How are these bits used?
Interface ID or interface identifier
They uniquely identify an interface on the local link
12. Name at least three tunneling protocols that are used for IPv6 packets to travel over an IPv4 network.
ISATAP
teredo
6TO4
13. How is an IPv6 address used that begins with 2000::? That begins with FE80::?
2000:: global address can be routed on the internet, these addresses are similar to IPv4 public IP addresses
FE80:: use for communicating with nodes in the same link
