How this service works
AAAA record of imap.<domain>: looks up the imap 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 imap without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the AAAA record for imap.<domain> exists, the IPv6 address records found, the TTL of those records, and the DNS response code (e.g. NOERROR or NXDOMAIN), as resolved by Cloudflare DNS over HTTPS.
Example use cases
Email server IPv6 readiness check
“Does imap.acmecorp.com have an IPv6 address set up? I want to know if the IMAP server supports IPv6 and what the TTL is on that record.”
Mail provider onboarding validation
“We're onboarding a customer at fastmail.com — can you confirm whether imap.fastmail.com resolves over IPv6 using Cloudflare's DNS?”
Infrastructure audit for IPv6 mail support
“I'm auditing our mail infrastructure — check if imap.ourcompany.org has an AAAA record and tell me what addresses it returns and how long they're cached.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/imap/aaaa?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, targeted IPv6 DNS existence check specifically for the imap subdomain of a domain without performing a broader subdomain enumeration. It is ideal for email infrastructure audits, mail server IPv6 readiness validation, and onboarding checks where you already know the subdomain pattern is 'imap' and want a single cheap lookup ($0.01) via the trusted Cloudflare DoH resolver.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- imap subdomain not configured for IPv6 — returns NXDOMAIN or empty AAAA result
- Malformed domain input — may return error or unexpected result
- Cloudflare DoH upstream unavailable — service may timeout or return error
- Rate limiting or payment failure — request rejected at x402 payment layer
