Point a hostname at your dollarbox

When a container is provisioned the control panel shows its public IPv6 address — something like 2a01:4f8:c2c:1234::5. To put a hostname in front of it, add a single AAAA record at your DNS provider.

Example

You own example.com and want app.example.com to point at your dollarbox.

That's the whole change. No CNAME, no flattening, no proxy. The container's IPv6 address is stable for the life of the container.

If you delete and recreate the container, you get a new IPv6 address. Update the AAAA record to match.

TTL

300–3600 seconds is sensible. Lower TTLs make IP changes propagate faster but cost more DNS queries. If your DNS provider has a default, it's almost certainly fine.

HTTPS

DollarBox does not terminate TLS for you. Run your own reverse proxy (Caddy is a one-liner) or bake TLS into your container directly. Let's Encrypt's HTTP-01 challenge does not work over IPv6 to all validators; use DNS-01 instead.
