 Load elpais.com over IPv6 from up to six other places — a second opinion.

What's keeping elpais.com from an A

  1. www.elpais.com is an alias of prisa-us-eu.map.fastly.net, which has no IPv6
    www.elpais.com is a CNAME, so it can't also have its own AAAA record. Ask whoever runs prisa-us-eu.map.fastly.net 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
    poster1i.iberlayer.com, poster2i.iberlayer.com, poster3i.iberlayer.com, poster4i.iberlayer.com 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.
