How this service works
AAAA record of www.<domain>: looks up the www 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 www without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the AAAA record for www.<domain> exists, the IPv6 address records found, the TTL value, and the DNS response code — allowing quick determination of IPv6 availability for the www host.
Example use cases
IPv6 readiness check for website
“Does www.shopify.com have an IPv6 address? I want to know if their www host has an AAAA record and what the TTL is.”
Pre-deployment DNS validation
“Before we go live, can you confirm that www.mynewstartup.io already has a valid AAAA record pointing to an IPv6 address?”
Troubleshoot IPv6 connectivity issue
“My users are having trouble reaching www.acmecorp.net over IPv6 — can you look up the AAAA record for that www host and tell me if it exists and what it says?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/www/aaaa?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to check the IPv6 (AAAA) DNS record for the www subdomain of a domain, rather than doing a general DNS lookup or enumerating all subdomains. It is ideal for quick, targeted existence checks of the most common web host prefix without broader subdomain enumeration.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- www subdomain has no AAAA record (only A record exists) — returns empty records with NOERROR
- Cloudflare DoH service is unreachable — network-level timeout or error
- Invalid domain format provided — may return an error or unexpected result
- Domain exists but www subdomain is not configured — returns empty or NXDOMAIN
