Using a Static IP Address on the CS Grad Nets

If you have requested a static IP address and been given one, here is how to use it on the CS networks.

Your IP address is on either the public grad net or the private grad net, depending on what you initially requested. (See Networking At CS - Overview for more information about our networks.) You must plug your system into an appropriate network jack for the network:

• For public addresses, use even-numbered jacks.
• For private addresses, use odd-numbered jacks.

If there are insufficient network jacks with the appropriate numbers in your area, please email support@cs.jhu.edu with the numbered jacks available to you and we'll see about getting one of them onto the appropriate network.

If you're using DHCP, which we recommend, and you indicated that use in your request, you should be able to just plug your system into the network and have it work. If your MAC address changes (e.g. you get a new computer or just a new NIC), you'll have to email support@cs.jhu.edu to let us know what the new MAC address is.

If you want to set your system up manually (and we recommend that you use DHCP instead), you can find information on the Connecting To The CS Grad Net Without DHCP page.

When you no longer need this IP address, please email support@cs.jhu.edu and let us know so that we can return it to the pool to be available for other requests.

If you have any questions or problems, with your IP address or anything else on the CS networks, please feel free to email support@cs.jhu.edu and we'll help you out.
