We have being concerned with creating more networks but work happens if we already have networks and want to create host on our networks? How then do we determine a valid IP for any host? For me, What am going to show you here is not much different from what we have done so far but in this case we are creating more host instead of networks. so lets take one scenario such as below:
An organization has this address 18.104.22.168 a class c address and want you to create 30 hosts from this network ooooh!
Using our binary chart 128 64 32 16 8 4 2 1
We are going to find out how many bit it will take us to get to number 30 and then we say that 30 = 00011110. This is = 5. Okay just like we did when looking for networks.
Step2 line up our subnet mask 255.255.255.0 = 11111111.11111111.11111111.00000000.
Note the difference here, instead of moving from left to right am moving from right to left to create more hosts.
So then 11111111.11111111.11111111.00000000
New subnet mask becomes 255.255.255.229
Here am saving the host and don’t care what is remaining, the other 3 zeros can go over to network address.
Step3 here will then find our increment using same method as in creating more networks
Our increment here is find in last network octet which is 32, recall that your increment is lowest network range.
So then our new hosts address will then be as follows:
22.214.171.124—–126.96.36.199 and so and forth and forth.
In this next tutorial I will solve one more example and then I will bring up a formula that will make your subnetting more simpler and faster at the same time.
