Campus DNS and DHCP Services

DNS
Domain Name Service is an Internet service that translates domain names into IP addresses and vice versa.

DHCP
Dynamic Host Configuration Protocol is a protocol for automatically assigning IP addresses to devices on a network using a defined range of numbers.

Domain
A domain is the end part of a hostname. For example, in the hostname www.example.umich.edu, the domain is example.umich.edu.

Subnet
A subnet is the beginning part of an IP address. A typical U-M IP address is 141.211.125.17. The subnet for this address is 141.211.125.

IPAM
Internet Protocol Address Management is a database system for planning, tracking, and managing IP address space.

The University of Michigan Hostmaster provides DNS and DHCP services using UMnet-supported BlueCat Networks appliances. BlueCat Database (Proteus) and DNS/DHCP (Adonis) servers are located in secure ITS Data Centers where they are quickly accessible and less vulnerable to power or network problems. Users manage and track their IP addresses and hostnames in real-time through an easy-to-use Proteus web interface.

DNS, DHCP and IPAM services are available at no cost to all campus units as part of the services provided by ITS Networking. The services are suitable for any unit that needs to assign and track IP addresses for their computers, printers, IP phones, or other devices that connect to the Internet.
