IP Subnetting
Read the following scenario and answer the questions that follow:
Netstack College has received a grant to wire all of its six buildings for 10/100 Ethernet. Four of the buildings contain classrooms and laboratories and will need to support 250 network connections each. One building is for administration and will need to support 180 network connections. The Administration Building also houses the Computer Center where the college servers and network backbone are located. The sixth building is the library, which must support 80 network connections.
You have been directed not to use a flat network of 1260 IP addresses assigned from a Class B network range. Instead, he would like to use multiple subnets.
Playing the role of the network administrator, what steps would you take to accomplish this setup using subnets instead of using a flat network of 1260 IP addresses assigned from a Class B network range? Determine and list the IP address ranges and masks associated with each building and explain the process you used to obtain the IP addresses and masks showing the obtained addresses and masks.
