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 130.126.2.100 (dns1.illinois.edu), 130.126.2.120 (dns2.illinois.edu), or 134.68.220.8 (dns1.iu.edu, Indiana University's name server), as these may not provide you the service you expect. The DNS map (Bluestem-protected) 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.
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.
