Connecting To The CS Grad Net Without DHCP

NOTE: The information on this page only applies to the networks in Malone Hall. This is page is not for people in Croft Hall or Shaffer Hall.

This page is for people who have filled out the IP address application, been approved, and are not using DHCP. We recommend using DHCP whenever possible. If you have not been given a static IP address, use the Connecting To The CS Grad Net Using DHCP instructions. If you have been given a static IP address and you want to use DHCP, simply configure your system to use DHCP and it will get all of its network configuration automatically.

Private Grad Net

For systems on the private network (which cannot be contacted directly from outside the Hopkins network), do the following:

Connect the system to a odd-numbered network jack. By default, odd-numbered jacks in Malone are designated for the private network. If that jack is either not working to put you on the Private network, please email support@cs.jhu.edu with the number of that network jack, and we will get it reassigned.

Configure your system with the following network information:

• IP Address: The address given to you by the CS IT group.
• Netmask: 255.255.255.0
• Default Gateway: 10.161.159.1
• Nameservers: 128.220.13.50, 10.200.2.2, 10.200.1.1 (If you only have room for two nameservers, just use the first two in this list.)
• Search Domain: cs.jhu.edu
• NTP Servers: ntp1.cs.jhu.edu, ntp2.cs.jhu.edu (NTP servers are optional.)

• Default Gateway: 128.220.35.1
• Nameservers: 128.220.13.50, 10.200.2.2, 10.200.1.1 (If you only have room for two nameservers, just use the first two in this list.)

Since your system will be exposed to the Internet at large, please make sure you keep it secured and its software up to date. The Hopkins Network Security team may periodically perform vulnerability scans of your system to double-check your security arrangements. (NOTE: JHU might block your IP access at the JHU Firewall if they find security issues with your system. JHU typically contacts the CS IT Support group to see who belongs to what machine, when JHU finds a security issue in a system. At that point, the CS IT Support group attempts to bring communication together between JHU and the owner of the system in question.)
