[Eril-l] IPv6 addresses for on-campus authentication - polling the group

[Electronic Resources in Libraries discussion list]

Thanks all who took the poll and responded. Not a huge sample, but nine out of fifteen respondents shared that they do share IPv6 ranges with e-resources platforms.

This question was partly motivated by learning from a major library vendor that their one of their primary systems can't accommodate IPv6 ranges - that made us wonder if we were somehow unique, but clearly we're not.

By the way, if anyone is interested, we've developed a couple tricks for troubleshooting IPv6 issues:


  1.
Browser extensions that tell you whether a particular connection is using v4 or v6. We use SixIndicator for Firefox and IPvFoo for Chrome.
  2.
Firefox makes it easy to disable IPv6 — if an on-campus connection doesn't work, but starts working after you disable IPv6, you've confirmed the problem. The instructions are here<https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can#w_ipv6>.

We share IP"v6 addresses if the provider takes them (not all do, last time we checked, but that was a couple of years ago — we haven't had to update our IP addresses in a while because the campus hasn't added any new address space.)

Hi all,

Our campus network dual-broadcasts both IPv6 (which look like for example 3492:130:101:500:adac:fc92:2229:5146) and IPv4 addresses (which look like for example 534.534.643.222), in some circumstances. For a few years now we've been dealing with issues where e-resources platforms start "reading" the IPv6 instead of the IPv4, causing access problems where the IPv6 ranges have not been registered.

A simple question for the community: For those institutions that are using on-campus IP authentication, do you share IPv6 campus ranges with e-resources platforms? I'm going to try to use a Microsoft poll, hopefully the listserv software doesn't reject it. While this is a simple yes/no poll, of course please chime in with any thoughts or experiences - we're really curious what this looks like for other libraries.
