You work as a junior network administrator and you have been tasked by the senior network administrator to devise a subnetting scheme for two of the company’s internal networks. Presently, the company owns the 9.0.0.0/8 network. The two sites you are required to restructure are the 9.7.208.0/20, and the 9.55.128.0/17 networks.

Task1

Devise a fixed-length subnetting scheme that divides the 9.7.208.0/20 network into four (4) usable subnets.
You should assume that the all zero's and all one's subnets are not usable.

Task2

Devise a fixed-length subnetting scheme that divides the 9.55.128.0/17 network such that each subnet can support a minimum of 1023 hosts.
You should assume that the all zero's and all one's subnets are usable.
