This tool is for penetration testing only. Never use a DNS resolver connected to the Internet on your IS.
Our VPN infrastructure is hosted on the Amazon EC2 & OVH clouds
open-source software: Java server, Flex client for Adobe AIR and Perl client are available on GitHub
Mail User AgentThe major feature of our application is providing you with a very fast native Mail User Agent, integrated with GMail, HotMail, OperaMail and YahooMail, specifically designed for DNS tunneling.
BrowserAnother main feature of our application is an optimized Browser. To be very fast, it does not download images, JavaScript, Cookies nor Cascading Style Sheets.
Port RedirectionAny legacy mail agent or browser will also work using TCP port redirection: we offer access to a full-featured web proxy agent (supporting images, JavaScript, Cookies & CSS) and tunnel SMTPs/IMAPs/POP3s, SSH and other services.
MonitoringYou can monitor the running DNS queries and replies, and also the download rate, by means of our nice dynamic vintage VU-meter laying at the top of the Status screen.
Users of VPN-over-DNS may want to analyse the WiFi coverage of some wireless networks. Here is a top 5 best WiFi heatmap software.
VPN-over-DNS is a free Android application delivered with a free account to connect to our VPN server farm.
In a few words, it lets you tunnel data through a DNS server.
Data exfiltration, for those times when everything else is blocked. Intended for Ethical Hackers.

The technology
The main advantage of this type of tunnel is that it does not require a direct Internet connection; you only need an access to a DNS resolver.
On the other hand, a major disadvantage is that this technology is often very
slow, even over a high speed network. Another main disadvantage
is that configuring the server is rather complicated.
Our solution
Our solution is extremely simple to install and use: you can start in less than 1 minute.
Firstly, you do not need to configure the server, we have already done it for you.
Secondly, our software includes a simple mail user agent and a basic text-mode web browser.
They are optimized for only two things: minimal configuration and being as fast as possible on such slow connections, when tunneling data over a DNS server.
Nevertheless, when you have time and you want to send/read mails with attachments or browse the Internet with pictures, on sites that exclusively work with browsers supporting
stuff like Cookies, SSL, CSS & JavaScript, you can simply use our port redirection feature. You will get a full-featured
Internet experience, over a DNS tunnel.
Other systems: Windows, Mac OS X, Unix, Linux & Docker
The VPN-over-DNS Windows and Mac OS X versions are named the Value Pack and both are available for free for our Android users: to install a DNS VPN client on your Windows laptop, click here, and on your Mac OS X laptop, click here. The Value Pack is based exactly on the same code than the Android version, except for the specific native implementation of DNS transactions.
The Perl open source version, targeting Unix, Linux, & Cygwin operating systems, is a complete rewrite of the VPN client and is available here. Registered Android users get advanced features using the Perl version (inbound and outbound mails queueing, free access to open proxies, ...) and anonymous users have access to basic features like SSH-over-DNS tunneling.
Many Unixes are supported: IBM/AIX, FreeBSD, Oracle/Solaris, ...
It also runs on Docker and is available from Docker Hub for instant deployment.
Blind hacker's DNS tunneling approach (Unix users only)
When you can access really nothing but dig (or nslookup) and a Perl runtime, not even root-level permission. And you need to set up a tunnel to the Internet. You can bootstrap a full VPN client and get Internet access only with dig (or nslookup) and a simple core Perl installation. Anywhere and whenever your need it. For free, using this hack.
