analysis DNS/Zone File Tools to Add to Your Domain Analysis Tool-Belt

[Eric Lyon]

An interesting topic idea was spawned from a reply in one of my other threads questioning the accuracy of different DNS/Zone file tool sites, so I decided to create a new topic to share a bunch of those tools for anyone interested. Thanks for the topic idea @NameGroove

With that said, let's jump right in and see what we find...

Below is a list of several websites and tools that offer functionalities similar to DNS/Zone file discovery. They let you explore, analyze, or even download DNS zone file data for various top-level domains (TLDs). These resources are popular among security researchers, domain analysts, and IT professionals who want an inside look at DNS records and trends.

A Few DNS/Zone File Tools​

1. DNS.Coffee
   • Description: A unique tool that collects and archives statistics from DNS zone files. It helps researchers and enthusiasts visualize trends in domain growth, distribution, and changes in DNS over time.
   • Link: dns.coffee
   • Reference: DNS.Coffee’s homepage directly shows its purpose .
2. SecurityTrails
   • Description: Offers a comprehensive view of DNS and domain data. In addition to historical records, SecurityTrails aggregates zone file–like data across numerous TLDs, making it invaluable for cybersecurity research and competitive intelligence.
   • Link: securitytrails.com
   • While primarily a commercial tool, its rich dataset is frequently used to supplement zone file research.
3. DNSDumpster
   • Description: A free online resource for mapping out the DNS infrastructure of a target domain. DNSDumpster performs passive DNS enumeration and can reveal aspects of the DNS “zone picture” that help in understanding how a domain is configured.
   • Link: dnsdumpster.com
   • Its focus on visualizing DNS relationships often overlaps with the kind of insight gained from complete zone file analysis.
4. ViewDNS.info
   • Description: A suite of DNS utilities—including DNS lookups, reverse DNS, and even zone transfer tests—that lets users inspect various parts of a domain’s DNS configuration. Although not a pure zone file downloader, its tools can be used to examine the components of a zone file.
   • Link: viewdns.info
5. WhoisXML API
   • Description: Provides several APIs and tools for domain and DNS research. Their Zone File API in particular offers access to detailed DNS zone file data for multiple TLDs. This is especially useful for market analysis, cybersecurity research, and large-scale analyses of domain records.
   • Link: whoisxmlapi.com
   • Note that many of its features work on a subscription basis or require registration.
6. DNSlytics
   • Description: Aggregates DNS, domain, and hosting data, offering visualized analyses that help reveal the underlying structure of a domain’s DNS. This tool can be very handy if you want an insight similar to what a full zone file might offer—showing relationships among various DNS records.
   • Link: dnslytics.com
7. Hackertarget DNS Tools
   • Description: Although not exclusively a zone file tool, Hackertarget hosts a collection of DNS utilities that provide critical insights into a domain’s configuration. Its DNS lookup and enumeration tools can help extract key aspects of a domain’s DNS setup, serving as a complement to traditional zone file data.
   • Link: hackertarget.com/dns-tools/
8. VeriSign Zone File Access
   • Description: For those specifically interested in the .com and .net TLDs, VeriSign offers a regulated process for zone file download. While not a “tool” in the casual sense, it provides official access to the raw zone file data maintained for the world’s largest TLDs. Registration and agreement to terms are required.
   • Link: https://www.verisign.com/en_US/channel-resources/domain-registry-products/zone-file/index.xhtml

Each of these resources offers its own set of features and data access methods, from free, web-based querying to subscription-based APIs that provide more in-depth and historical data. If you’re diving into domain research, testing your network security, or even just curious about DNS trends, these tools can vastly broaden your perspective.

Additional Tools of Interest

If you’re interested in expanding your tool-belt further, you might explore these related areas:

• DNS Security Tools: Websites such as Cloudflare’s DNS Security page and BIND's documentation provide insights into DNS security best practices, including DNSSEC.
• Domain Research Platforms: Platforms like DomainTools and RiskIQ PassiveTotal offer deep dives into domain ownership history and digital footprints.
• APIs for Bulk DNS Data: In addition to WhoisXML API, consider checking out other bulk data providers if you're into data-driven investigations of the DNS ecosystem.

I find that many of the tools above are great for in-depth analysis of multiple domain related segments in our industry. If you like digging into data, crunching numbers, and leveraging data for speculation, the above tools might have a spot on your tool-belt.

For me, viewdns.info was particular interesting with an array of different tools.

Remember, at the end of the day, a domain name is truly only worth what a buyer and seller agree on.

What works for one may not work for another and vice versa.

Happy Domaining!

Wow some fantastic tools that I did not know about in this post. Thanks so much, @Eric Lyon !

The drop in number of TLDs in the graph on the main page of DNS.coffee is interesting. I presume that is because of companies that have stopped hosting their brand as a new gTLD, or at least mainly.

Thanks so much – I plan to look into these useful resources!
