Private local numbering

June 22, 2013

The internal IP addresses of the computer science machines are from the 172.16.0.0/12 address block which is then subnetted by security level to an overall 172.16.0.0/16 address. Currently there are four security levels – public, sandbox, lab and servers, but this summer we will collapse public and sandbox into a single level.
