What's keeping mail.rutgers.edu from an A

  1. mail.rutgers.edu is an alias of email.rutgers.edu, which has no IPv6
    mail.rutgers.edu is a CNAME, so it can't also have its own AAAA record. Ask whoever runs email.rutgers.edu to enable IPv6 there — or replace the alias with the A and AAAA records they give you. Why some hosts don't offer IPv6
  2. Mail servers without IPv6
    mx.lists.rutgers.edu, mxkb.lists.rutgers.edu have no AAAA record, so mail from IPv6-only servers can't reach them directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.

What this means

Visitors on IPv6-only networks (many mobile carriers) can still reach it, but only through a translator their carrier runs (NAT64). The site itself has no IPv6 address — and you can't make one up from the IPv4. Why some hosts don't offer it
