DNS lookups should be fast, clean, and private
We built ZonePeek because most DNS tools are either cluttered with ads, slow to load, or quietly logging every domain you search. We wanted something better — a tool we would actually use ourselves.
Why we built this
ZonePeek started as an internal tool at JTB Media, a web development studio based in the Netherlands. We manage DNS for dozens of client domains — configuring mail servers, verifying SPF records, debugging propagation delays, migrating between hosting providers. Every week we found ourselves bouncing between multiple DNS tools, each with their own quirks.
Some tools only showed A records unless you paid. Others wrapped results in so many banner ads that the actual data was hard to find. Most had no export option, which meant copy-pasting records one by one during migrations. And none of them let us easily compare what Google DNS sees versus Cloudflare — a check we run constantly to verify propagation.
So we built what we needed: a single tool that queries all 10 common record types at once, lets you switch between resolvers in one click, and exports selected records as a ready-to-use BIND zone file. No sign-up, no paywall, no tracking. We liked it enough to put it online for everyone.
How it works under the hood
When you enter a domain, ZonePeek sends parallel queries for 10 DNS record types — A, AAAA, CNAME, MX, TXT, NS, SOA, SRV, CAA, and PTR — to the public DNS resolver you selected. We use the DNS-over-HTTPS (DoH) APIs provided by Google Public DNS and Cloudflare DNS (1.1.1.1).
Every query goes directly from our server to the resolver and back. We don't cache results, we don't store queries, and we don't log the domains you look up. The response you see is exactly what the resolver returned at that moment — nothing filtered, nothing modified.
The export feature generates standard BIND zone file syntax, the same format used by most DNS hosting providers. This means you can take the output and import it directly into Cloudflare, AWS Route 53, DigitalOcean, or any provider that accepts zone files.
What makes ZonePeek different
All records at once
One query returns all 10 record types. Most tools make you select and query each type separately, which costs time when you need the full picture.
Compare resolvers
Switch between Google DNS and Cloudflare DNS with one click. Useful for verifying that DNS changes have propagated across major resolvers.
BIND zone file export
Select any combination of records and export them as a standard BIND zone file. No more copy-pasting individual records during provider migrations.
No tracking, ever
Zero cookies, zero analytics, zero stored queries. We don't know what domains you look up. Read our privacy policy for the full details.
Built by JTB Media
ZonePeek is built and maintained by JTB Media, a web development and IT services studio based in Drenthe, the Netherlands. We build websites, manage hosting infrastructure, and handle technical SEO for businesses across the region.
Working with DNS is part of our daily routine — from configuring MX records for new email setups to debugging DMARC policies and managing multi-domain hosting environments. ZonePeek is a direct product of that hands-on experience.
Open and transparent
ZonePeek is built with Next.js and deployed on Vercel's edge network for fast response times worldwide. The DNS queries use the official DNS-over-HTTPS endpoints from Google (dns.google) and Cloudflare (cloudflare-dns.com), both of which are free, public, and well-documented services.
We chose these two resolvers specifically because they are the most widely used public DNS services in the world, with the best uptime records and the most transparent privacy policies. When you see a result in ZonePeek, you can trust it matches what these resolvers actually return.
