How this service works
AAAA record of login.<domain>: looks up the login 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 login without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the login.<domain> AAAA record exists, the IPv6 address(es) in the record, and the TTL value, as answered by Cloudflare DoH.
Example use cases
IPv6 login portal existence check
“Does login.shopify.com have an IPv6 AAAA record? I want to know if their login subdomain is reachable over IPv6 and what TTL it has.”
Security audit of login infrastructure
“Check if login.acme-corp.com has an AAAA record — I'm auditing their DNS to see whether their login host is dual-stack or IPv4 only.”
Competitor login host reconnaissance
“Does login.notion.so resolve via IPv6? Pull the AAAA record and tell me the address and TTL if it exists.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/login/aaaa?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted IPv6 DNS existence check specifically for the login subdomain of a given domain, without needing to enumerate all subdomains. Prefer it over generic DNS lookup tools when you want a focused, pay-per-lookup check via Cloudflare DoH with no infrastructure setup required.
Side effects
- Domain does not exist — returns no records found
- login subdomain has no AAAA record (may only have A record) — returns empty result
- Invalid domain format provided — may return error or empty response
- Cloudflare DoH upstream timeout — service may return error
- Rate limiting or payment failure — 402 response if payment not attached
