For any computer to connect to the Internet via CU-Boulder - whether from a
lab, an office, or your home - the TCP/IP setup must contain the correct
DNS nameservers. The DNS system translates between computer
hostnames and their corresponding IP addresses. For example, the host
ucsu.colorado.edu has the corresponding IP address
220.127.116.11. Rather than requiring you to memorize this long
string of numbers, DNS allows you to instead use the simpler hostname to
access the computer.
You do not need to enter any DNS servers in your configuration if you are
connecting to the network via DHCP. DNS servers are automatically configured
by the DHCP protocol.
More than one name server should always be specified so that if the first one
is unavailable, another one will be used.
The order of nameservers listed in your setup is not critical, but to spread
the load out across the campus, you should choose one of these ordered sets
based on the location of your computer.
NOTE: Some system managers may prefer to designate a nameserver that they
administer (or know is located on the subnet) as the first nameserver in
their setup. In such cases, simply use one of the below ITS nameservers as
the second and/or third choice.
If you are in the Engineering Area use the following:
Campus Name Server addresses [Engineering] (enter in this order):
If you are located on Main Campus use the following:
Campus Name Server addresses [Main Campus] (enter in this order):
For East Campus users, use:
Campus Name Server addresses [East Campus] (enter in this order):
