DNS Found
DNS Found groups records discovered during analysis, including common hosts, security TXT records, and useful audit traces.
This section is not a full DNS zone export. It shows what DNSprobe observed while running the main checks and probing a few common names.
It helps spot subdomains, CNAMEs, validation TXT records, Microsoft 365 or Google Workspace traces, and unexpected configuration leftovers.
1. Overview
DNS Found consolidates DNS answers collected during the report to provide a practical view of discovered names.
Results may include standard names such as mail, www, autodiscover, common DKIM selectors, and specialized TXT records.
2. What DNSprobe checks
DNSprobe adds answers found by DNS, mail, and web sections, then scans selected frequently used hosts.
- A, AAAA, CNAME, MX, TXT, SRV, and PTR records encountered during checks.
- Common configuration traces such as Microsoft 365, Google Workspace, DKIM, DMARC, MTA-STS, and TLS-RPT.
- Highlighting of DNS wildcards or records that may explain false positives.
3. Interpreting results
A record appearing in DNS Found means it was observed, not necessarily that it is recommended.
- An expected known host often confirms that the corresponding service is published.
- An old provider or forgotten subdomain can reveal configuration debt.
- A DNS wildcard can make subdomains appear even when they are not individually configured.
4. Best practices
- Remove validation TXT and CNAME records that are no longer used.
- Avoid exposing unnecessary administrative subdomains on the public internet.
- Document legitimate subdomains and their internal owner.
- Audit DNS wildcards before concluding that a subdomain truly exists.
5. Manual tests
Test a few common names with dig.
dig A www.example.com +short
dig CNAME autodiscover.example.com +short
dig TXT _dmarc.example.com +short
dig SRV _sip._tls.example.com +shortDNS Found is a diagnostic aid; an authorized zone transfer or DNS control panel access is still needed for a complete inventory.
