What's keeping stage.mastercard.com from an A

  1. stage.mastercard.com is an alias of e16745.x.akamaiedge.net, which has no IPv6
    stage.mastercard.com is a CNAME, so it can't also have its own AAAA record. Ask whoever runs e16745.x.akamaiedge.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

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
