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.

CITES IPAM News

Posted Wed 07/16/14

On Thu Jul 24, 2014 between 10:00pm-12:00am, the production Infoblox grid for the campus IPAM (DNS and DHCP) service will be upgraded from its current software version (6.5.0) to the latest release from the vendor (6.10.6).

Important Reminder for API Users

After the upgrade date, you will need to update your installation of the Infoblox API perl modules on any client systems that you use to run Infoblox API scripts against the production grid. Note that this upgrade cannot be applied to your production environments ahead of time; see the service documentation (http://www.cites.illinois.edu/ipam/api.html) for further explanation.

DNS Server IP addresses

The DNS resolver address for campus is:

         130.126.2.131

Note: please do NOT configure your computer to use 130.126.2.100 (dns1.illinois.edu), 130.126.2.120 (dns2.illinois.edu), or 204.93.1.5 (dns3.illinois.edu). These are authoritative-only servers which will not be able to answer queries for external domain names such as google.com, so a computer using these DNS servers will not be able to navigate the Internet correctly.

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.

The Campus IPAM Web Appliance (documentation / login )

This section explains how to access the campus IPAM web appliance and how to perform common DNS-related configuration tasks with it, including Host registration, MX records and CNAME assignment.

Domain Requests

This page explains how to apply if you have a University-related need for either a .edu subdomain (sample.illinois.edu or sample.uillinois.edu) or a non-.edu domain (.org, .com, etc.) and how to transfer your domain name to the University.

Bulk changes to DNS entries

If you have 10 or more changes to make to a domain you can import them using .csv files in the format described on this page.
