Network Proposal for Mountain Sky Elementary School

Katie GotshallShane Neff

Todd RowlettRyan ShafferRachel Stull

Problem Statement

Students, teachers, and administrators need an easy to use, fast and secure access to the Internet, academic services available on the school’s intranet, and a central location in which to store the school system’s applications and student data.

Network Requirements

• 1000% LAN growth, 100% WAN

• Only two protocols (TCP/IP and IPX)

• Internet access to all nodes

• School must have two distinct LANs

• Internal and External Security

• DHCP address assignment

• Access Control Lists on routers

Project Constraints

• Money

• Time

District IP Addressing

• The district will be assigned a Class C address.

• The district will use Network Address Translation (NAT) to achieve a 10.0.0.0 network

• Subnet mask of 255.255.0.0 yields 256 networks with over 65,000 host per network

Mountain Sky IP Addressing

Mountain Sky will be designated 3 networks of which one will be the connection to the district hub. All networks have a 255.255.0.0 subnet mask.

• 10.37.0.0—Student LAN

• 10.38.0.0—Administrative LAN

• 10.166.0.0—Connection to District Hub

Access Control Lists (ACLs)

DHCP IP Address Assignment

• A DHCP server will be used to assign IP addresses for both students and administrators.

• The administrators’ range of IP addresses will be defined as ‘statically automatic’ meaning each machine will receive the same address each time

• This will allow for the DHCP to also function as an application server and lessen the burden placed on the school’s IT staff

IPX Addressing Scheme

The IPX addressing scheme will use the subnet portion of the IP address for the host address and the MAC address of the host belonging to that network as the host portion of the address.
