What's keeping frontlane.app from an A

  1. Give frontlane.app 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.frontlane.app is hosted on Vercel, which has no IPv6
    It points at cname.vercel-dns.com, and that name has no AAAA record — so nothing you add in your own DNS can give it IPv6. Put an IPv6-capable proxy in front (Cloudflare's proxied DNS does this), or host somewhere that offers IPv6. Which platforms offer IPv6
  3. Mail servers without IPv6
    Your domain's mail goes to its own address, which has no AAAA record.

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
