Record each subnet number on paper, starting with the first subnet (0), until the last subnet number is greater than the IP address whose type is to be determined. After recording the subnet number, list out its directed broadcast address next to the subnet number (as mentioned earlier, the directed broadcast address is smaller than the next subnet number by1). You do not need to do this for each subnet number, but only for the subnet numbers near the IP address whose type you want to determine. 6. Write out the host address between the subnet number and the directed broadcast address (all addresses between the subnet number and the directed broadcast address are host addresses).Using these 6 steps, you should be able to determine whether the given address is a network host address, a network address, or a directed broadcast address. Notice that these 6 steps are somewhat like the 6 steps presented in the previous section, but these steps are used for the CCNA exam, whereas the steps in the previous section were used for IP address planning.Exam Essentials Keep in mind the 6 steps for determining whether an IP address is a network address, a host address, or a directed broadcast address.6.4.2 IP Address Type Determination Example 1To help you understand the 6 steps, see an example demonstration. In step 1, given the IP address and subnet mask, assume they are 192.168.1.37 255.255.255.224 ( 192.168.1.37/27), which is a Class C address. Keep in mind the following trick: If the address is odd, it is either a directed broadcast address or a host address, and not a network address.Exam point Please keep the following trick in mind: the network number is always even, the broadcast address is always odd, and the host address may be odd or even. Based on these criteria, some incorrect answers can usually be eliminated QIn step 2, you need to find the relevant byte in the subnet mask, i.e. the byte where the boundary between the network part and the host part is located. In this example, the relevant byte is the 4th byte (224 ) o In step 3, it is necessary to find out how much the subnet numbers of the adjacent subnets differ. To do this, subtract the value of 256 from the associated byte: 256 - 224 = 32O That is, each subnet contains 32 addresses, and the associated byte (4th byte) of the adjacent subnet number differs by 32 OExam Point Keep in mind the shortcut for calculating how much the associated bytes of adjacent subnet numbers differ: value of the difference = 256 - value of the associated byte of the subnet mask.In step 4, list the subnet numbers one by one, starting with the first subnet. In this example, the subnet numbers are as follows: 192.168XPLEX 0, 192.168.1.32, 192.168.1.64, 192.168.1.96, 192.168.1.128, 192.168.1.160, 192.168.1.192 and 192.168.1.224. In this example, there are 8 subnets In this example, there are 8 subnets, which is consistent with the laws of mathematics: each subnet contains 32 addresses, and the Class C network contains a total of 256 addresses (0 to 255), so the number of subnets is 256: 32 = 8! Don't forget that the value of the subnet mask is the same as the value of the last subnet number in the relevant byte.
