What's keeping mobile.uchicago.edu from an A

Nameservers without IPv6
ucns1.uchicago.yale.edu, ucns1.uchicago.uiowa.edu, ucns3.uchicago.edu, ucns4.uchicago.edu all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.
