According to your example:-
Step 1: Calculate total number of subnet. How to calculate ?
number of subnet = 2 ^n n means number of borrow bits
In this case , you have borrowed 5 bits from host part , so total number of subnets are as following:-
number of subnet = 2^5
number of subnet = 32
And each subnet is having 8 ip addresses.
Step 2: Calculate network id and broadcast id for each subnet with the help of block size. Now the question is that how to calculate block size. Very simple. we can also represent /29 to 255.255.255.248. To calculate block size , you have to subtract the last octet value from 255.
Block size = 255-248 = 7
How to calculate Network and Broadcast id ??
192.168.10.0 255.255.255.248
start from zero
192.168.10.0 /29 Network id for 1st subnet
To calculate Broadcast ID, add block size in the octet , which is having the subnet bits. In this case, Add block size in last octet.
192.168.10.7/29 Broadcast ID
2nd subnet
192.168.10.8/29 - Network ID
192.168.10.15/29- Broadcast ID
3rd subnet
192.168.10.16/29 Network ID
192.168.10.23/29 Broadcast ID
At the end
Last subnet
192.168.10.248/29 Network ID
192.168.10.255/29 Broadcast ID
