Category:Networking

This category covers how to connect your own computer (desktop/laptop) to the CS Network.

There are two main networks in CS, the CS Grad/Research Net and the CS Undergrad Net. Both have their own IP ranges and can only be connected to via an ethernet (Cat 5e or better) cable.

CS Grad/Research Network

You may connect to the CS Grad/Research Network via wallports in most CS offices and labs, except for Croft (formerly, NEB) 225/227 (the CS Collaboration Room and CS Undergraduate Lab).

You may request a static IP for the CS Grad/Research Network by filling out and submitting the CS Network IP Address Application form. You will need to get a CS faculty member to approve/sponsor you getting a static IP, and list that faculty member in the appropriate field of the form. When you fill out the form, we will contact the faculty member you listed to confirm approval. Please a allow a few business days for the form to be processed.

You may also choose to use a DHCP-provided non-static (dynamic) IP instead.

CS Undergrad Network IPs

The CS Undergrad Network is only available via wallports in NEB 225/227 (the CS Collaboration Room and CS Undergraduate Lab). and only using CS's Dynamic DHCP service for the Ugrad Net. There are no static IPs granted to users for the CS Ugrad Net.

DNS Servers to use when on the CS Network

Primary DNS: 128.220.13.50

Secondary DNS: either 10.200.1.1 or 10.200.2.2 -- your choice.

DHCP-provided CS IPs will automatically receive a primary DNS server of 128.220.13.50 and a secondary DNS server of 10.200.2.2.

Wireless

CS does not provide wireless capability. We suggest connecting to JHU's hopkins wireless network if you would like to wirelessly connect to JHU. (We recommend you do not connect to JHU's "JHGuestnet" access point, since it limits your ability to connect to sites within JHU. So, use "hopkins" instead.)

If you have problems connecting to JHU's "hopkins" wireless system, you can either contact the JHU Helpdesk at 410-516-HELP or, you can send e-mail to wirelessteam@jhu.edu for further assistance. Be sure to tell them where on campus you are experiencing the problem. They might also require specific information about your computer, including its wireless interface's MAC address.

Security Note

All computers that connect to the CS Grad/Research or Undergrad net should be at their latest security levels and should be configured to prevent viruses, etc. For antivirus software, please see the JHU Antivirus webpage.
