Wired network service is available in academic and administrative buildings on the Ithaca campus, as well as in some remote offices via Cornell Network Extension. 

Cornell Information Technologies (CIT) provides universal services for all wired connections to the campus network including:

  • Ethernet access to the Cornell network backbone. The target service level for the network backbone is 99.999%.
  • Redundant connections to the Internet and national research and education networks.
  • Overall traffic and capacity management.
  • Domain Name Services.
  • DHCP service for departments that elect to use it.
  • 24/7 monitoring for security breaches and outside attacks.
  • Routing for IP (Internet Protocol).

Wired network connections in offices or classrooms are activated upon request by the department.

You can also connect to Cornell's network over Wi-Fi (including eduroam) and, for secure access when you're off-campus, through CU VPN (Virtual Private Network).

CIT also maintains dedicated high-speed network connections to Weill Cornell Medical Center and the Cornell Tech campus to promote collaboration between the campuses.
