IP Subnet Split Calculator
IP Subnet Split Calculator, What can this calculator can perform ?
For Example you are a local Network Administrator for a branch Office in Singapore , the Headquarter Office Network Administrator in US provide you An IP address and Net mask 10.128.192.0 /19 .
You are ask to subdivided the Network , into 30 Separate Subnet
This Calculator will help you perform the Job
How Subnet Split being Calculated
For Example your head quarter provided the Following information below
10.128.192.0 /19 .
and ask you to the Local Network Administrator to Split that into 30 Different Separate Network
Step 1
Split the Net work and the Host Portion
Step 2
Check how many Bits you need to steal from the Host
you are ask to create 30 Sub nets
What is the Nearest 2 power of n , which is equal to 32 ?
30 = 2n
There are no value for 2 power of n equals to 30 , the nearest is n=5
so the Result should be 32
Step 3
Now we know we need to borrow 5 bits from the host to create a 32 subnets
So if you convert the Net Mask into Binary you will get a New Net Mask 255.255.255.0
Step 4
Now you got your new Net mask ,
You can Calculate the Rest
1) Wild Card
2) BroadCast Address
3) Number of Subnet
4) Number of Host
5) First IP address for the ” Enter IP” Network.
6) Last IP Address for the ” Enter IP” Network.
