A. 10101010 B.00011100 C.11110010 D.10100111
4. What is the full subnet mask for address 192.168.10.10/28?
5. You have the following address: 192.168.5.99/29. How many total bits are being
used to identify the network, and how many total bits identify the host?
6. You still are using the default mask for your IP network 192.168.1.0. You need to
subnet your network so that you have 4 additional networks, and 60 hosts per
network. Is this possible, and what subnet mask should you use?
7. You currently use the default mask for your IP network 192.168.1.0. You need to
subnet your network so that you have 30 additional networks, and 4 usable hosts
per network. Is this possible, and what subnet mask should you use?
8. You have sub-netted your class C network 192.168.10.0 with a subnet mask of
255.255.255.224. Please list the following: number of networks, number of hosts
per network, network address, broadcast address, the full range of the first four
networks, and the usable address range from those first four networks.
9. You have sub-netted your class C network 200.138.1.0 with a subnet mask of
255.255.255.252. Please list the following: number of networks, number of hosts
per network, the full range of the first three networks, and the usable address
range from those first three networks. Additionally, identify the broadcast
addresses for each network.
