37) This last subnetting problem is a challenge. Write out your calculations on paper, like youve done in previous steps. In this scenario, your PC has been assigned the 172.20.0.129 address in a /25 network. Write out the default subnet mask and determine how many bits have been borrowed.

38) Based on the subnet mask, determine the size of the subnet blocks.

39) Starting with 172.20.0.0, write out the first six subnet numbers.

40) Write out the directed broadcast addresses for the first four subnets.

41) Write out the host ranges for the first four subnets.
