The University is running out of IPv4 in a number of areas due to the current addressing scheme being to granular. This was done to help with billing internet usage in the past. The University needs to create free IP addressing space through consolidating IP addressing, especially to deal with the current growth in BYOD technologies. Staff and students are now using more than one device connected to the wireless infrastructure.

In 2015 La Trobe University expects to have over 25,000 concurrent wireless devices connected to the Infrastructure during peak periods. The public IP addressing space is being reserved for Students, Staff, Researchers and Guests networks on Wireless. The wired network is currently being used for VOIP, Computer LABs, Audio Visual, Security, Servers and Research equipment.

You only need to make allowance for Research Equipment, Servers (Virtual IP) and Computer Labs to remain on the Public IP addressing scheme.

Redesign the University IP addressing space. The University owns 2 x Class B (144.149.0.0 and 131.172.0.0) IPv4 Public IP addressing space and also utilizes IPv4 Private IP addresses including 10.0.0.0 and 192.168.0.0.

Design an addressing scheme that best utilizes the addresses available and simplify management whilst ensuring the best security in the design. Your design needs to cater for the following.

1) Sites
Bundoora - 64000 IP Addresses
Bendigo - 16000 IP Addresses
Wodonga - 4000 IP Addresses
MilduraDeakinstreet - 800 IP Addresses
Mildura TAFE - 400 IP Addresses
Franklin Street - 800 IP Addresses
City Campuses - 800 IP Addresses
Austin Hospital - 400 IP Addresses
Alfred Hospital - 400 IP Addresses
3rd Party Networks (Research Bundoora) 12 x 60 IP Addresses
3rd Party Networks (Research Bendigo) 4 x 100 IP Addresses
3rd Party Networks (Research Wondoga) 1 x 100 IP Addresses

2) Other than at Research Locations at least 50% of the IP addressing needs to be allocated to Wireless services.

3) The network needs to be able to distinguish between staff, researchers and students networks.

4) The wired Connections are broken down into VOIP 20%, Computers\LABs 40%, Audio Visual 5%, Security 10%, Servers 15%, Research Equipment 5% and Printers 5%.

5) Servers should not be directly able to be accessed from their IP address to the Internet and typically are accessed via a load balancer devices which has a Virtual IP allocated for external access.

6) Printers and Security must not be accessible via the internet or student networks.
