IPv6-accessible DNS in higher education

| | Comments (0) | TrackBacks (0)

A few months ago, I blogged that only two of the Big 10 schools have IPv6-reachable authoritative DNS servers. Things are a little better now: Indiana University has IPv6 DNS servers, bringing the total to three Big Ten schools.

I wanted to see how other grouping of US higher-ed institutions faired. In the CSG, things are the same: 3 of the 26 members (PSU, IU and UCSD) have IPv6 DNS.

Things are slightly better in Internet2: 12 of their 209 university members have IPv6-accessible DNS servers:

  • Indiana University
  • Pennsylvania State University
  • Princeton University
  • University of California, Berkeley
  • University of California, San Diego
  • University of Delaware
  • University of Illinois at Urbana-Champaign
  • University of Notre Dame
  • University of Oregon
  • University of Pennsylvania
  • University of South Florida
  • Wichita State University

Note that Internet2 itself does not have IPv6-accessible DNS. Which is very strange, since they've routed IPv6 across their network for at least 4 years. Also note that not all schools on the above list have IPv6 themselves. In some cases, an IPv6-capable third-party is providing DNS. For example, Princeton does not have IPv6, but one of their backup DNS servers (ns3.nic.fr.) has IPv6.
