Farsight Security's GUI for making DNSDB queries, available for Mozilla's Browser

DNSDB Scout™ for Firefox supports all the major features of the DNSDB® API including:

  • Query Results: Displays up to 50,000 results.
  • API Status: Tracks, displays, and updates your API key usage automatically.

  • Limit Record Types: DNSDB contains a vast number of DNS records. Only need MX records or AAAA records? Limit your queries to only get the results you need.

1. What are the prerequisites for using DNSDB Scout for Firefox?

To use the DNSDB Scout Extension you must first have the Mozilla Firefox web browser installed on your system. DNSDB Scout should work on any operating system that can run an up-to-date version of Firefox with native extension support. Unfortunately, that means iOS isn't supported at this time.

You also need a valid DNSDB API key. DNSDB API keys are portable, so if you already have one, you are ready to go. You can also sign up for a 30-day free trial right form within DNSDB Scout, or by visiting https://www.fasightsecurity.com/trial-api/

2. What is the difference between DNSDB Scout for Firefox and the Chrome version?

The only substantial difference is the Firefox version allows for a maximum of 50,000 query results to be displayed at a time as opposed to 10,000 in the Chrome version.

3. How do I install DNSDB Scout for Firefox?

As with all current Mozilla Firefox extensions, they must be obtained and installed via the official Mozilla Add-ons site.

You can search the site for 'DNSDB' or 'Farsight', or by visiting https://addons.mozilla.org/en-US/firefox/addon/farsight-dnsdb-scout/

4. Are there any limitations with DNSDB Scout for Firefox?

Since a Mozilla Firefox extension runs inside your browser, it competes for system resources just like any other browser window or tab.

The maximum number of results a DNSDB API call can return is 1,000,000. In order to manage browser performance responsiveness, DNSDB Scout for Firefox has a maximum limit of 50,000 results.
