How this service works
A record of img.<domain>: looks up the img host under the domain you give (A via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like img without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the img.<domain> A record exists, the resolved IP address(es), the TTL of the record, and the DNS response code. If the subdomain does not exist, it reports that no records were found.
Example use cases
CDN image subdomain verification
“Does shopify.com have an img subdomain set up? I want to know its IP address and how long the DNS record is cached.”
Website infrastructure audit
“I'm auditing the DNS setup for acmecorp.com — can you check if their img subdomain has an A record configured and what it resolves to?”
Pre-deployment DNS check
“We're about to launch and I need to confirm that img.mybrand.com has its A record properly set before going live — can you look that up?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/img/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted existence check for the img subdomain of a specific domain without doing broad subdomain enumeration. It is ideal for infrastructure audits, pre-launch DNS validation, or automated monitoring of whether a domain has an image-serving host configured. Prefer this over general A-record endpoints when you specifically want the img host, and over full subdomain scanners when you only need this single common hostname.
Side effects
- Domain does not have an img subdomain — returns NXDOMAIN or empty records
- Malformed domain input — may return an error or no results
- Transient Cloudflare DoH failure — may return a timeout or DNS server error
- Payment not processed — request blocked before DNS lookup occurs
