NetQuery provides public DNS, email security, SMTP, TLS, DNSSEC, IP and Microsoft 365 diagnostics. These guides focus on practical investigation workflows rather than isolated record definitions.
- Troubleshoot email delivery, work from MX and SMTP through SPF, DKIM, DMARC, TLS and reverse DNS.
- Troubleshoot DNS and DNSSEC, separate delegation and record problems from DNSSEC chain-of-trust failures.
- Investigate IP addresses and CIDR ranges, connect subnet boundaries, ASN ownership, PTR, FCrDNS, geolocation and reputation.
- Use NetQuery in Microsoft 365, run diagnostics in Teams, Outlook and Microsoft 365 Copilot.
- Lookup and command examples, quick syntax for common NetQuery requests.
