FastDNS Overview

FastDNS by is a free tool designed to help you identify potential slow downs in your network caused by DNS speed. If you firewall, servers, or workstations are using a DNS server that is performing slow then you Internet access speed may be slow as well. This tool allows you to customize your own DNS settings and test its speed on resolving domain names. We recommend testing your ISPs DNS and any local DNS servers you may be running as well.

Features Include

» Pre-built public DNS server list to test.
» Ability to add / edit / delete the DNS servers you wish to test.
» Testing is performed in just a few seconds.
» Results are automatically sorted by fastest to slowest server.
» And it is 100% free (no nag screens, malware, or hidden surprises)


Who is this application designed for?
Typically network administrators and IT consultants will get the most value out of this application.

Why is this tool free?
We had developed this tool internal to help our managed firewall customers identify slow downs on their networks. We found it to be so useful for network admins and consultants that we decided to package it up at no cost.

Do I have to register?
No. Click the download button and you are good to go.

No. All of the features are available and there is no need to buy anything.
