Chapter 6.5 IP Networking

Which of the following is a valid IP address?

172.16.1.26
2.2.2.2
A valid IPv4 address consists of 4 8-bit (1 byte) numbers separated by periods. For example, 10.0.0.65. Because they are 8 bits long, these numbers are frequently called octets. Even though we typically express these numbers using deci

Which of the following IP address are Class C addresses?

192.15.5.55
223.16.5.0
222.55.0.0
The following are class C addresses: 192.15.5.55, 22.55.0.0, and 223.16.5.0.
The first octet of Class C addresses is in the range of 192 to 223.
The first octet of Class A addresses range from 1-126.
The first octet of Cl

Which of the following IP addresses belong to the Class A network 114.0.0.0?

114.0.0.15
114.58.12.0
114.122.66.12
With a Class A network, the first octet indicates the network address. All hosts on the network must have the same value in the first octet (114).

Which of the following IP addresses have a default subnet mask of 255.255.0.0?

129.0.0.1
191.168.2.15
168.16.5.1
IP addresses are divided into classes. The most common of these are classes A, B, and C. Each address class has a different default subnet mask. To identify the class of an IP address, look at its first octet. Class A net

Which of the following IP address ranges is reserved for Automatic Private IP Addressing?

169.254.0.1 - 169.254.255.254
The Internet Assigned Numbers Authority (IANA) has reserved 169.254.0.1 through 169.254.255.254 for Automatic Private IP Addressing (APIPA). APIPA also sets the subnet mask on the network to 255.255.0.0.

You have a small home network that uses 192.168.1.0 with the default subnet mask for the network address. The default gateway address is 192.168.1254, the router is providing DHCP on the network. The Wrk2 computer has been assigned to IP address of 192.16

127.0.0.1
127.0.0.1 is the loopback address for any device. This special address means "this host." If you ping the lookback address, TCP/IP configuration will be tested. A successful test means that TCP/IP is correctly configured on the host. 192.168.1.5
