CITES DNS Service

This section contains information about the CITES DNS (Domain Name System) service and its interface. Most of this information is for IT professionals; end users should only need the campus DNS server's IP address.

DNS Server IP addresses

As of August 2008, the DNS resolver address for campus is:

         130.126.2.131

The old campus DNS servers, 128.174.5.58 (argus.cso.uiuc.edu) and 128.174.5.102 (cyclops.cso.uiuc.edu), are no longer in service and were retired on July 31, 2009.

If you are located on campus, do NOT use 128.174.5.103 (dns1.cso.uiuc.edu), 128.174.5.104 (dns2.cso.uiuc.edu), or 134.68.220.9 (dns1.iu.edu, Indiana University's name server), as these will not provide you the service you expect. The DNS map gives a graphical representation of how the campus DNS machines interact with the outside world and campus machines.

DNS for users

DNS Basics explains what a DNS server is used for and which IP addresses are used for the campus DNS servers. Most users won't need to change their own computer's DNS settings, however.

DNS for IT professionals

IT professionals will use the campus DNS servers much more extensively than users, in order to create subnetworks, control access to these subnetworks, reassign addresses within their network space, and create groups for use with the campus firewall system.

Info iconTransitioning from uiuc.edu to illinois.edu

On behalf of Chancellor Richard Herman,  Public Affairs is coordinating the transition of the Urbana campus domain name from uiuc.edu to illinois.edu. More information about this initiative is available at the Illinois Domain Project Overview and Illinois Domain Project forum.

Any unit that has an existing domain in uiuc.edu (unitname.uiuc.edu) will be given the rights to the same domain name in illinois.edu (in other words, moving from unitname.uiuc.edu to unitname.illinois.edu). Requests to change to a different domain (oldname.uiuc.edu to newname.illinois.edu) will be handled separately.

After November 1, 2008, IT pros can submit an Illinois.edu domain change form to change a unitname.uiuc.edu domain to its unitname.illinois.edu replacement.

Due to the volume of domains to be changed, the turnaround time for UIUC to Illinois domain changes is expected to be two weeks.

Domain requests

The Illinois.edu domain request form is to request subdomains in the uiuc.edu or illinois.edu domains.

The non-Illinois.edu domain request form is to request non-illinois.edu domains for campus-relevant sites (under other top-level domains such as .org, .com, etc).

The Campus DNS Web Appliance (documentation / login )

This section of the DNS documentation explains how to access the campus DNS web appliance and how to perform common DNS-related configuration tasks with it, including host registration and CNAME assignment.

Bulk changes to DNS entries

If you have 10 or more changes to make to a domain, submit them to hostmgr@illinois.edu in the format described in DNS Bulk Changes.

DNS Tools

This section lists the rest of the DNS-related tools available to campus IT professionals.

Customized or Personalized Domains

This page explains how to apply if you have a University-related need for either a customized subdomain (sample.illinois.edu or sample.uillinois.edu) or a personalized domain (sample.org or sample.com).

On-campus IP ranges

This page documents the various IP ranges available to computers that belong to on-campus networks.

Campus DNS Standards

This page provides implementation details related to the campus domain registration policy.
