Before continuing, please read Networking at CS - Overview to find out more about our network configurations before continuing. (We assume you've read that page before you continue to the next sections here.)

This page deals only with the process needed to obtain a static IP address on the CS networks. At this time, static IP addresses are only granted on the CS Grad/Research Nets. If you're connecting to the CS Ugrad net, follow the instructions at Connecting to the CS Ugrad Net. If you're connecting to the CS Grad nets but don't need a static IP address, you may follow the simpler instructions for dynamic IP addresses at Connecting to the CS Grad Nets.

A static IP address requires approval from a member of the CS faculty. Please make sure you obtain approval before sending your request.

Decisions, decisions...

You will need to decide a few things about your future static IP address.

First, you must to decide whether it will be on the public or private grad net. The differences are detailed in our overview, but the most salient one is that private addresses can only be contacted from within the Hopkins network or VPN.

Second, you must decide how you will configure your system to use its new IP address, whether you will use DHCP to automatically receive your network configuration or whether you will manually enter all of the information yourself. We recommend using DHCP whenever possible because it reduces the amount of work you have to do and means that you'll automatically receive any network configuration changes as soon as we make them. (Your home Internet connection probably uses DHCP for its network configuration.)

Requesting the IP Address

Fill out the CS Network IP Address Application.

We will contact the faculty member you list on the form to verify we can provide you a static IP address.

Once approved, we will email you with IP address information.

You may then use the information at Using a Static IP Address on the CS Grad Nets to set your computer up with its new IP address.
