What's keeping static.npmjs.com from an A

  1. Add IPv6 for www.static.npmjs.com
    www.static.npmjs.com has no AAAA record. Get www's IPv6 address from whoever hosts www and add it as an AAAA record. If the same server already serves both names (and its certificate covers www), you can reuse static.npmjs.com's AAAA record(s) for www. How to add an AAAA record
