Hello Deepika1312,

Welcome to the Monastery. What you have tried and where you have failed? Show us your sample of code, input and expected output.

From a quick search on the web I have found a few modules that could possibly help you, have you tried those? For example similar question calculate subnet help, this is good starting point.

Looking forward to your reply, BR.
