What's keeping roblox.com from an A

  1. Give roblox.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.roblox.com is an alias of edge-term4-lax2.roblox.com, which has no IPv6
    www.roblox.com is a CNAME, so it can't also have its own AAAA record. Ask whoever runs edge-term4-lax2.roblox.com 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. Nameservers without IPv6
    nspx1.roblox.com, nspx2.roblox.net, nspx3.roblox.us, nspx4.roblox.co.uk all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.

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
