DNS Records
WHOIS / Registration
Registration data planned
Registrar, creation/expiry dates and domain status via RDAP. Rolling out gradually — bulk WHOIS is rate-limited, so we resolve on a prioritized cadence.
Subdomains
Every subdomain we know about — harvested from CT-log SANs, scan-observed certs and HTML body references — paired with its current A/AAAA target.
| Subdomain | Resolves to | Last seen |
|---|---|---|
| ccard.dnschecker.org | 2026-07-18 21:15:21.466 | |
| dnschecker.org | 2026-07-28 10:49:00.176 | |

Tech Stack
Tech detection pending
Wappalyzer-rules detect CMS, frameworks, analytics, JS libs and server-side languages on this domain.
TLS Certificates
Certificate observations pending
TLS certs naming this domain in subject or SANs will appear here as our scan-layer catches them.
IPs Citing This Domain
Hosts whose HTML body references this domain. Strong signal for origin/mirror/embed discovery.
Origin / IP-Leak
When a hostname is served behind a CDN (e.g. Cloudflare), the origin server can sometimes be identified by matching its TLS cert against the protected hostname. Findings shown here are heuristic candidates, not guarantees.
| Origin IP | Origin ASN | CDN ASN | Confidence | Reasoning |
|---|---|---|---|---|
| 104.248.5.79 | AS14061 | AS13335 | 95% | cert d5544883… served by 104.248.5.79 (AS14061) carries SAN dnschecker.org which currently resolves through Cloudflare (AS13335) at 104.26.7.89, 104.26.6.89, 172.67.73.216, 2606:4700:20::681a:759 |
Threat Intelligence

Matches in URLhaus, OpenPhish, PhishTank, malware feeds, and Spamhaus DBL.
History
Domain timeline pending
Passive-DNS history accumulates as our forward-DNS crawler observes A/AAAA/MX/NS/TXT records over time.
