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
Split the Net work and the Host Portion
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
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
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.
