1. How many bits are in a MAC address? 48 bits.
2. How many bits are in an IPv4 IP address? In an IPv6 IP address? 32 bits and 128 bits.
3. How does a client application identify a server application on another computer on the network? By the port number, port, or port address.
4. What are the IP addresses called that begin with 10, 172.16, 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 licensed and authorized to use the Internet. Private IP addresses are not authorized or licensed to use the Internet. A computer with a private IP address uses a proxy server to access the Internet.
8. Why is it unlikely that you will find the IP address 192.168.250.10 on the internet? Because it’s a private IP address.
9. In figure 9-9, the subnet mask is four notches tall and is considered a classless subnet mask for this network of sticks. How many notches tall would be a classful subnet mask for the same network? 2 notches tall.
10. 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? Static IP address.
11. If a computer is found to have an IP address of 169.254.1.1, what can you assume about how it received that IP address? The IP address was automatically assigned by Windows when it failed to lease an address from the DHCP server.
12. What are the last 64 bits of an IPv6 IP address called? How are these bits used? Interface ID. For identifying the network.
13. Name at least three tunneling protocols that are used for IPv6 packets to travel over an IPv4 network. ISATAP, Teredo, and 6TO4.
