MIT students, faculty or staff with valid Kerberos identities may request a permanent reserved IP for use in an MIT building.
On this page:
You can do so by:
- Submitting a query on an online form
- Using the hostinfo command on Athena .
For example, to find the IP address for a machine with the host name bitsy and the domain name mit.edu, you could log into Athena, and at the athena% prompt, enter the command
If the hostname already exists, you will receive information about the hostname
Permanent reserved IPs and host names can be requested in a few ways, depending on where the IP address will be used:
If the permanent reserved IP address will be used in a dorm by a student, a request should be submitted by filling out the Hostname Request form.
If the permanent reserved IP address will be used in a Fraternity, Sorority, or other living group (FSILGs), you should speak with the [Network Contact] for your house to have this created.
If the permanent reserved IP Address will be used in an Academic building, the Request 1-4 permanent reserved IPs form may be used to submit the request.
Note that, among other information, this form asks for a cost object for tracking purposes. As of 2009, IP addresses are no longer charged for. however IS&T will use the cost object and the machine contacts to keep track of the IP addresses. Students should get this information from a contact in their DLC if they do not know it.
You can also request for IP addresses by sending an email to email@example.com. Be sure to include ALL the following information for each machine that requires an IP address:
Information must be complete and submitted in either plain text or Microsoft Excel format.
If you need help regarding IP addresses, host names, or connecting devices to MITnet, you can contact the IS&T Service Desk
