**A records**. The current fleet is IPv4-only: keep `SERVER_IPV6` empty and do not create
AAAA records. Create these two names in your DNS provider's console/API:

| `<DOMAIN_ROOT>` | AAAA | `SERVER_IPV6` | off (skip if no IPv6) |
| `*.<DOMAIN_ROOT>` | AAAA | `SERVER_IPV6` | off |
Notes:
- Keep them **unproxied** — the node terminates its own TLS and needs the real client IP path; a proxy/CDN in front would break the WS cover and the panel anti-scan logic.

If your zone is on Cloudflare, skip the manual step — `02-cf-dns.py` upserts the two A
records when `SERVER_IPV6` is empty (`CF_API_TOKEN` with `Zone:DNS:Edit`). Run it from wherever the
token lives; it never touches the VPS.
Leaving `SERVER_IPV6` empty does **not** delete existing AAAA records. For an existing
node, back up DNS records, remove the AAAA records under that node's domain, then check
the API and public DNS. See [IPv4-only fleet policy](../../../../docs/EDGE-IPV4-ONLY.md).

## Cloudflare WARP
- **Disabling host IPv6 does not disable IPv6 inside WARP's proxy tunnel.** Keep the IPv4-only guards in Xray and sing-box: force IPv4 domain resolution and reject `::/0` before WARP routing. `UseIPv4` can fall back to system resolution in Xray; use `ForceIPv4`. Do not pass unresolved target domains to WARP. See [fleet policy](../../../../docs/EDGE-IPV4-ONLY.md).
- **`gpg` must be installed first.** On a minimal Debian, `gpg --dearmor` for the repo keyring fails with `gpg: command not found`, and the later `apt update` then errors `Failed to parse keyring … sqv returned an error code`. `apt-get install -y gnupg` before adding the repo.
- Use the **`bookworm`** repo line even on Debian 13 (trixie) — the bookworm package works.
- **WARP can lie about being connected.** The control plane shows `Connected` while the SOCKS proxy stops egressing. The watchdog (`warp-healthcheck.*`) checks `warp=on` *through the proxy* and restarts `warp-svc` when it isn't.
