Network

Networks assigned to Math Student Org Net.

IPv4 / IPv6

All of the CSC's public networks are fully dual-stack; this means all of our services are offered over both IPv4 and IPv6.

May-June 2017 Networking Changes

The CSC network is currently undergoing major changes.

A highlight:

• Two routers: mc-rt-3015-mso-a and dc-rt-3558-mso-a
  • Routers will be configured with VRRP for CSC/MSO networks
  • Networks will be interconnected by a 1Gbps link (until an additional 10Gbps card + transceivers are acquired)
