9. Given 3 bits of mask for the host portion, how many host addresses are available? 10. Given 8 bits of mask for the network portion, how many subnets are available? 11.
I Exercise 8.1.1 Class A networks are defined as those that use only the first byte ( also called an octet) of the address as the network identifier. The rest of the address is considered the host identifier. In this type of network, the number of possible networks is much smaller than the number of hosts that can be connected to the same network. If the IP address in Figure 8- 1 belongs to a class A network, what is the network ID and what is the host ID? 110 (network ID), 10.10.1 (host) What are the binary values of the host ID and the network ID?
They allow 16,384 networks by using the first two octets in the address for the network identification. The first two bits of the first octet are fixed to 1 0. The next 6 bits along with the following octet then complete the network identification. The third and fourth octet (16 bits) then represents the host ID. This allows approximately 65,000 hosts per network.
a) netstat -an b) ipconfig /tcp c) nslookup d) tracert 11. Which one of the following mask could create an IP subnet from a Class B network that could contain 500 hosts? a) 255.255.255.0 b) 255.255.254.0 c) 255.255.255.128 d)

192.168.0.0/22 10. Refer to the exhibit. What are two of the routes added to the routing table of R1? (Choose two.) R 192.168.1.0/24 [120/1] via 172.16.2.1, 00:00:24,
There are approximately 4.3 billion IPv4 addresses available. 3.) Approximately how many IPv6 addresses are possible? There are 340,282,366,920,938,463,463,374,607,431,768,211,456 Ipv6 addresses available 4.) Why do you think the world is running out of IPv4 addresses?
| Question 4 | What is the name of the computer you are working from? SEA-SVR2 | Question 5 | What IP addressing settings are currently configured?10.10.0.12 | Question 6 | Is the computer currently configured for DHCP? How can you tell? Yes, DHCP enabled and it received an ip address of 10.10.0.20 | Question 7 | What is the IP address of the DHCP server from which W2K8yy has obtained its IP address? DHCP Server 10.10.0.11 | Question 8 | If the answer to #7 was not the IP address of the SEA-SVR1 computer, why might this have happened?
