still remember how to find hosts that can be used, and a broadcast network with a binary? In fact, there is the easy way without having to convert to binary first, by using the formula 256 - subnet values, for example, we can ip 192.168.0.18/29, what network? broadcast? and how many ip that can be used?
ok, let's find, still remember how to find prefix? if you forget, please read here
/ 29 means 255.255.255.248, which note is that the value is not equal to 255, subtract that value by 256
256 to 248 = 8
needs in mind, the reduction is the key, K = 8. well, after it noticed its ip address, 192.168.0.18, key values must be at times the numbers do not exceed the value of the ip, in the example is 18, so 8 * 2 = 16, because 8 * 3 = 24 is higher than ip. 18. is already on to the network, well, to find the ip that can be used first, just add ip network + 1 = 17.After was broadcast live on the search, how, (Key + Network) - 1 = 23, to search for the last ip, live broadcast - 1 = 22.
