Network Addresses

UMNet Administration coordinates the networking infrastructure and network numbers. A Standard Practice Guide policy for Internet Addressing: IP Address Standards provides information about addressing at the university.

  • The addresses listed below are external IP addresses which are reachable from inside and outside the university.
  • For information on private IP addressing (e.g., addresses which are reachable only inside the university), refer to the Private IP Network Numbers page.
  • Michigan Medicine network IP addresses of 141.214.x.y are administered by the Health Information & Technology Services group.

New IP Block Added for MWireless

Due to the continued growth of WiFi across the UM-Ann Arbor campus, ITS is adding a new block of IP address space (*) to the ​MWireless network. The addition of new IP address space will help ensure the availability of MWireless across campus as use of WiFi continues to grow. The targeted timeline for introducing this new address space is spring/early summer.

Important Information on IP Filtering

For those who may be filtering access to resources by IP addresses used by MWireless, please know that you will need to ​include the network by the end of March to help ensure a seamless introduction.
