Domain Name System

Domain Name System (DNS) converts web addresses into numeric IP addresses. For example, DNS translates into the IP address "" DNS is required for the computing infrastructure.


  • Authoritative Name Service
    Additional second-level domains can be managed for Carnegie Mellon affiliates upon request. These domains require registration with a domain registrar (e.g., Network Solutions, GoDaddy). Computing Services provides DNS service for approved, CMU-affiliated external domains. Domain owners accept full responsibility for technical, administrative and billing-related management of the registered domain.
  • Dynamic Host Configuration Protocol (DHCP)
    Networked computers or hosts automatically obtain Internet Protocol (IP) addresses and other network attributes, such as the default gateway router, subnet mask and DNS servers.
  • Third-level Domain Name
    Name immediately before in a computer's full name and indicate the department owner or administrator.
