Domain Name System (DNS) & Dynamic Host Configuration Protocol (DHCP)

University Services

  • Domain Name System (DNS) is an Internet service that translates domain names (e.g., its.umich.edu) into IP addresses. 
  • Dynamic Host Configuration Protocol (DHCP) is a protocol for automatically assigning IP addresses and other configurations to devices when they connect to a network. 
  • Internet Protocol Address Management (IPAM) is a database system for planning, tracking, and managing IP address space.

The university hostmaster provides DNS, DHCP, and IPAM services at no additional cost as part of the larger networking services on campus. These services allow units to assign and track IP addresses for computers, printers, IP phones, or other devices. 

DNS and DHCP services are managed using BlueCat Network appliances. BlueCat Address Manager (Proteus) and DNS/DHCP (Adonis) servers are located in core network locations and university Data Centers. Users track and manage their IP addresses and hostnames (e.g., www.its.umich.edu) in an easy-to-use web interface.
