How this service works
A record of forum.<domain>: looks up the forum 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 forum without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the forum.<domain> A record exists, the resolved IPv4 address(es), and the TTL of the DNS record. If the subdomain does not exist, reports that it was not found.
Example use cases
Verify forum infrastructure before outreach
“Before I reach out to the team at mozilla.org, can you check if they have a forum set up? Look up the A record for forum.mozilla.org and tell me if it exists and what IP it resolves to.”
Competitor forum presence check
“I'm doing competitive research — does Shopify have a forum subdomain? Check the DNS A record for forum.shopify.com and let me know if it exists and what TTL it has.”
Pre-deployment DNS validation
“I'm setting up forum.mycompany.com — can you double-check that the A record for forum.mycompany.com is already resolving correctly in DNS before we go live?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/forum/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a targeted, single-subdomain existence check for the 'forum' host under a given domain without enumerating all subdomains. Prefer this over general DNS tools when you specifically want to confirm whether a domain runs a forum at the standard forum.<domain> convention and need IPv4 (A record) resolution via Cloudflare DoH for reliability and privacy.
Side effects
- Domain does not exist — no DNS records returned
- forum subdomain not configured — NXDOMAIN or empty answer
- Cloudflare DoH service unreachable — upstream timeout or error
- Malformed domain input causes query failure
- Rate limiting or payment failure for the $0.01 per lookup fee
