Answer the questions based on the above Internet Protocol Address (IPA) and MASK

1. How many Subnet will be created from the borrowed Host bits (2 to the power of borrowed bits) ?

2. What is the Total Host Address Per Subnet (2 to the power of un-borrowed bits )?

3. How many Valid/Available Host IDs Per Subnet (2 to the power of un-borrowed bits - 2)?

4. What is the subnet block size/increment, it is the value of the last host bit borrowed (default 255)?

5. Build the network IPA scope, show the first 8 and Last subnets with full IPA ranges?
