How this service works
AAAA record of pop3.<domain>: looks up the pop3 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 pop3 without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the pop3.<domain> AAAA record exists, the IPv6 address(es) in the record, the TTL value, and the DNS response code (e.g. NOERROR, NXDOMAIN) as resolved by Cloudflare DoH.
Example use cases
Email server IPv6 audit
“Check if pop3.acmecorp.com has an AAAA record in DNS — I'm auditing our mail infrastructure to make sure the POP3 server is IPv6-reachable.”
Pre-migration connectivity check
“Before we migrate our mail clients to IPv6, can you verify whether pop3.mybusiness.net is set up with an AAAA record and what its TTL is?”
Third-party domain mail host verification
“I need to confirm that pop3.vendordomain.com actually exists in DNS with an IPv6 record — can you do a quick AAAA lookup for that subdomain?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/pop3/aaaa?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to check the IPv6 (AAAA) DNS record for the pop3 subdomain of a domain — ideal for email infrastructure audits, IPv6 readiness checks, or quickly verifying whether a POP3 mail host exists without doing full subdomain enumeration. Prefer this over generic DNS tools when you want a targeted, single-host check resolved via Cloudflare's trusted DoH resolver.
Side effects
- Domain does not exist — NXDOMAIN response returned with no records
- pop3 subdomain not configured — NOERROR but empty answer section
- Invalid or malformed domain input — request may fail or return an error
- Cloudflare DoH upstream timeout or unavailability — lookup may time out
- Domain has only A (IPv4) records, not AAAA — response will show no AAAA records
