How this service works
AAAA record of ftp.<domain>: looks up the ftp host under the domain you give (AAAA via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like ftp without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the AAAA record for ftp.<domain> exists, along with the IPv6 address records and their TTL as resolved by Cloudflare DNS over HTTPS.
Example use cases
Verify IPv6 FTP server reachability
“Check if ftp.mycompany.com has an AAAA DNS record — I need to know if our FTP server is reachable over IPv6 and what the TTL is.”
Pre-migration IPv6 readiness audit
“Before we migrate our infrastructure to IPv6, can you check whether ftp.oldinfra.net has an AAAA record configured in DNS?”
Detect FTP subdomain presence on competitor domain
“Does ftp.acmecorp.com have an IPv6 DNS record? I want to know if they're running an FTP host and whether it's IPv6-enabled.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/ftp/aaaa?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to check IPv6 (AAAA) DNS records for the ftp subdomain of a domain, without needing to enumerate all subdomains. Prefer this over general DNS tools when you want a fast, targeted existence check for the ftp host with Cloudflare's DoH resolver and a per-lookup micropayment model.
Side effects
- Domain does not exist — returns non-existent/NXDOMAIN status
- ftp subdomain has no AAAA record — returns empty records with exists=false
- Invalid or malformed domain input — may return error or empty response
- Cloudflare DoH upstream timeout — may return error or no data
- Domain has only A (IPv4) records for ftp, not AAAA — returns no AAAA records found
