Network and Wireless
TIG provides support for the data network throughout the entire Stata Center with the exception of the Student Street and certain areas below ground. The CSAIL wireless network serves all floors in the Gates tower, and all CSAIL areas in the Dreyfoos tower (D6 and below), but does not serve the first-floor classrooms or “student street”. This is very different from most of the rest of campus, which relies entirely on MITNet.
The CSAIL network provides gigabit Ethernet at a density of one port per 25 square feet of office space, for a grand total of about 4,000 gigabit network ports. The network backbone is 100-gigabit Ethernet with two redundant backbone switches; the link between the core switches is 200 Gbit/s. CSAIL has aggregate outside connectivity of 10 Gbit/s.
DHCP is provided throughout the network, except in areas where research groups have opted to run their own DHCP server. By default, every blue-colored data jack in offices and open lab areas is “live”, meaning that it is connected to the network, enabled, and will provide an IP address, DNS server info, netmask, and other necessary information via DHCP. In seminar rooms and certain other public spaces, only certain drops are live.
There is no need to register or do anything other than just plug your computer in with an ethernet cable, or connect to CSAIL Wireless. In order to print you need to connect to CSAILPrivate. We can provide an ethernet cable if you don’t have one.
CSAIL’s network also extends to the Massachusetts Green High-Performance Computing Center in Holyoke over a private 10-gigabit link with layer-3 redundancy.

Requesting a static IP address
- To request a static IP address, follow the directions in the
WebDNS Users Guide to register your desired hostname. WebDNS (
CSAIL Login required)
will assign you a static IP address. You can then use DHREG (
CSAIL Login required) to
register your MAC address for the IP address WebDNS gave you.

Technology and configuration
- VNC setup from outside CSAIL
- VPN access to CSAIL is no longer provided or supported. If you need VPN access, first you may want to ask yourself the question, “Do I really need VPN access?” If you are unsure, please ask TIG. You may want to consider MIT’s VPN: http://vpn.mit.edu/
If you need a VOIP phone setup in your space, need to update caller ID, or reset pin, email your request to firstname.lastname@example.org. We generally only set up one device per office or space but if needed can add additional lines.
For more information on using the MIT VOIP phones see the MITvoip Telephone User Guide
