What's keeping klarna.com from an A

  1. Give klarna.com an IPv6 address
    Ask your hosting provider for the site's IPv6 address (or the hostname to point at), then publish it as an AAAA record. If your host doesn't offer IPv6, a proxy that does can sit in front. How to add an AAAA record
  2. www.klarna.com is an alias of klarna.production.us1.one-web-platform.klarna.net, which has no IPv6
    www.klarna.com is a CNAME, so it can't also have its own AAAA record. Ask whoever runs klarna.production.us1.one-web-platform.klarna.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
  3. Mail servers without IPv6
    mxz4.klarna.com, mxz2.klarna.com, mxz3.klarna.com, mxz1.klarna.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.

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
