Domain Name Service

Domain name service provides lookup services for campus-connected hosts. It translates names such as www.cmu.edu to the Internet Protocol (IP) address. The IP address is necessary for establishing a connection to a machine.

Note: DNS is no longer available from off-campus.

Campus Nameservers

Users at Carnegie Mellon are encouraged to use DHCP rather than statically configuring machines. By using DHCP, any necessary changes to the DNS servers will be transparent. Should the need arise to statically configure a machine, however, the following campus nameservers should be used:

Hostname	IP Address
ac-cdns1.net.cmu.edu	128.2.1.10
ac-cdns2.ns.net.cmu.edu	128.2.1.11

 

Authoritative Nameservice

The Network Group maintains additional servers for authoritative DNS, serving domains such as cmu.edu, cmu.net, and reverse service for the campus 128.2.0.0 prefix.

Additionally, the Network Group can, upon request, manage additional second-level domains for Carnegie Mellon affiliates. These domains require registration with a domain registrar (such as Verisign). We can manage this process and configure these domains on campus nameservers.

For more information about Network Group hosting of a domain, please contact net-dev@andrew.cmu.edu. Using the Network Group to host your additional domains provides you the ability to manage registrations in the domain using NetReg, the campus machine registration system.
