SCS Computing Facilities supports most networking throughout the School of Computer Science — services including desktop connectivity, DHCP, domain-name service, Virtual Private Networking (VPN), dialup access — plus planning and maintenance of the SCS network infrastructure.

We are currently reallocating our IP addresses. This process will prepare the SCS address space for computers that will be located within the new Gates Technology Center. Please refer to the IP-reallocation project details.


See our network use policies for rules for network use and for policies concerning host names, domains, and the creation of virtual web hosts.


There is no firewall between SCS and the rest of the internet. Potential intruders scan each host on the SCS network many times per day, looking for security vulnerabilities. To compute safely in our open environment, please become familiar with our security documentation.

DSL & cable remote access

We do not provide any "broadband" (DSL, cable, etc) networking services for remote access; neither does CMU Computing Services.

Remote Access

  • VPN
  • iPass
    • iPass is a global network of dialup and broadband internet access points.
