For questions 9 and 10 you have a network 128.64.112.0/20 and you want to subnet it.

9. If you wanted to subnet 128.64.112.0/20 into 4 networks of 1024 addresses (each supporting 1022 hosts) what would the the 4 sub-network addresses be? I'm looking for 4 subnets specified as XX.XX.XX.XX/YY.

10. If you wanted to further subnet only ONE of the 4 networks above into networks of 64 address (supporting 62 hosts) what would the new netmask be? How many sub-networks would you create?
