Hi @Khasim Pathan,
Based on your original question, I used the following site which provided both the IPv4 and IPv6 subnet.
https://www.calculator.net/ip-subnet-calculator.html
Re multiple addresses - How are you getting on? As you've probably realized, it's a little more involved with a few variables in play when working out subnets. You'll probably have to write a script to do this for you.
How many are you referring to?
So as to help others and based on your original question, please mark my earlier response correct by clicking on Accept as Solution and/or Helpful.
Thanks, Robbie
