Resolver-Aware Comparisons
Compare Cloudflare, Google, Quad9, or ZenaConsult authoritative servers to prove propagation state and catch stale answers.
Professional DNS Lookup, SPF/DKIM/DMARC Checker
DNS Inspector provides a complete, static DNS overview that Google can crawl and index. This page performs authoritative DNS lookups, SPF chain expansion, DKIM selector checks, DMARC policy validation, DNSSEC inspection, MX/NS analysis, and stores each run as a server-side snapshot you can revisit — all without requiring any JavaScript execution. You can also email yourself a personal recovery link so clearing cookies never strands your historical insight. The tool helps engineers diagnose mail delivery issues, propagation delays, and nameserver inconsistencies using real resolver data.
Whether you manage domains, run hosting infrastructure, or troubleshoot mail flow, DNS Inspector offers a fast, reliable and globally consistent DNS view that can now be compared over time with one-click historical snapshots and recoverable share links.
Advanced DNS Monitoring, SPF, DKIM & DMARC Intelligence
ZenaConsult DNS Inspector is a technical SEO, email deliverability, and drop-watch companion that surfaces nameserver misconfigurations, missing SPF includes, DKIM selector issues, DMARC alignment gaps, DNSSEC status, WHOIS lifecycle data, expired-domain states, and now preserves each run as a server-hosted snapshot. Every scan runs on fast public resolvers or your own custom IP so you can document how the internet really sees your domain, compare historical outputs from the collapsible snapshots panel, and email yourself a recovery link to reactivate access from any device.
Email Security Deep Dive
Expand SPF trees, inspect DKIM selectors, verify DMARC enforcement, and confirm PTR symmetry before hitting send.
Service Discovery Radar
Automatically enumerate MX, SRV, autodiscover, and webmail endpoints to map every touchpoint clients rely on.
Drop Watch + Snatch
Automatically flag redemption or pending-delete statuses and jump straight into OVH to backorder the domain before competitors do.

Understand Your DNS Footprint Before Launch
DNS Inspector provides a complete snapshot of the DNS records that govern how mail, web, and security services behave for any domain or subdomain. Enter a domain above to query live data and translate it into human-friendly remediation insights.
Choose from well-known public resolvers (or your own custom IP) to see how different networks resolve the domain. When ZenaConsult hosts the zone, you can enable the compare view to contrast our internal resolvers with the public internet and catch propagation delays quickly.
- Survey NS, MX, TXT/SPF, DKIM, DMARC, SRV, and service-discovery records in a single report.
- Detect DNSSEC, CDN/WAF providers, and common mail platforms automatically.
- Export, print, or share results directly from the toolbar once a scan completes.
- Monitor WHOIS status changes (redemption, pending-delete, expired) and jump into OVH backorders immediately.
How to Use DNS Inspector for Maximum Impact
Follow these fast steps to baseline DNS health before migrations, new launches, or ongoing deliverability monitoring.
- Enter your domain and select a resolver. Use Cloudflare, Google, Quad9, or your branch office resolver to replicate real-world clients.
- Toggle ZenaConsult comparisons when eligible. Instantly validate whether authoritative answers on asterix.zenahost.it or panoramix.zenahost.it match the public web.
- Review the security stack. Inspect SPF includes, DKIM selectors, DMARC policy, DNSSEC status, PTR records, and automated suggestions for red flags.
- Capture historical evidence. Use the Historical Snapshots panel to save the full report to our secure server store, then email yourself a recovery link so the history follows you anywhere.
- Share or export evidence. Copy a smart link, print the PDF-friendly layout, or download the TXT report to attach to change tickets.
DNS Inspector FAQ
What does DNS Inspector analyze?
It collects NS, MX, TXT, SPF, DKIM, DMARC, SRV, DNSSEC, and WHOIS signals to give you a consolidated view of web, email, and security records.
Can I compare public and private resolvers?
Yes. Hosted ZenaConsult zones unlock an instant comparison between Cloudflare, Google, or any custom resolver and our asterix/panoramix infrastructure to reveal propagation gaps.
How does this help email deliverability?
By validating SPF trees, DKIM selectors, DMARC enforcement, PTR symmetry, and IPv6 coverage you eliminate the DNS errors that trigger spam filtering or bounce backs.
Can I save and compare historical snapshots?
Absolutely. Every lookup can be saved to a private server-side store tied to your browser, letting you compare resolvers across time, prove fixes to stakeholders, or catch unexpected record drift. Email yourself the recovery link from the snapshots panel to reopen that history even if you switch devices or clear cookies.
