dig aaaa ns.snarked.org @a0.org.afilias-nst.info +short
I don't get an answer, and we aren't considering Additional an answer, as it isn't a host record the TLD has, but rather reaching out to the NS in Authority and asking.
I'm still looking into this, because it makes no sense why registering with someone like GoDaddy (or other places, but I use them) for .com and .net get glue (host records in the TLDs) and .org doesn't even seem to do this with ipv4, which would be a .org TLD thing and probably not the registrar.
Not sure why .ORG TLDs don't reply for either IPv4/6 host records, unless they do some whacky internal referencing just to fill in the AUTHORITY section which then fills in ADDITIONAL. I suppose I'll send an email in hopes of a reply for an answer from them.
Last edit for a while, I've emailed pir.org directly asking them about glue etc. If/when I get a reply, hopefully that will either resolve issues, or at least give us better direction for testing .ORG domains for glue. Until then .COM and .NET do not appear to have issues and should get to Sage.
