Network Address Management: IPv6 History at the University of Minnesota

IPv6 is a type of IP address that utilizes a 128-bit network address, allowing for a nearly infinite amount of unique addresses. The standard for IPv6 was created in December of 1998 and finally became a recognized Internet Standard in July of 2017. Below are some of the landmarks in the University of Minnesota's adoption and implementation of IPv6.

IPv6 at the University of Minnesota

OIT enabled IPv6 within Northern Lights GigaPOP in early 2003 via Internet2.

OIT has been testing IPv6 in the lab and on a limited number of subnets on and off since 2003.

  • NTS and OITSec have been running IPv6 on engineering subnets constantly for about five years.

IPv6 support was a requirement of the design and the selection of hardware for Gopher GigaNet in 2004.

  • IPv6 support is now mostly mature in the Cisco 3750s and 6500s upon which the GGN is built.

OIT has provided Native IPv6 connectivity for IETF and other technical meetings held in Minneapolis.

OIT did an IPv6 trial with TW Telecom the 4th quarter of 2008 through the 2nd quarter 2009.

Northern Lights GigaPOP now uses TW Telecom as a production commercial IPv6 ISP.

GigaPOP IPv6 Connectivity

  • Interent2, NLR, TW Telecom, ESNet
  • CIC OmniPOP participants
  • ND, SD, and several other NLG participants

IPv6 has been enabled for Authoritative DNS.

IPv6 has been enabled on the entire Twin Cities campus backbone.

  • The backbone is ready to enable IPv6 on most VLANs.

IPv6 is available across most of the campus via "eduroam" wireless SSID.

  • Anyone with an IPv6 and WPA2 capable device with a Internet ID login should be able to access the IPv6 Internet.

IPv6 subnets are available to the community. IPv6 is included, along with IPv4 for any new subnet request created after December 30, 2011.
