DeSopa – DNS Evasion to Stop Oppressive Policy in America

DeSopa Firefox AddOnPowerful special interests are attempting to force legislation for tighter control of the Internet, because they believe such legislation will preserve their power. The bill they have sponsored, SOPA (Stop Online Piracy Act), not only has severe consequences for the Internet, it doesn’t even achieve their objectives.

The internet creates market efficiencies that forces industries to adapt, thus pushing forward progress for humanity as a whole. Public freedoms should not be curtailed and the Internet, built by the masses, should not be destroyed, so that a powerful few may have a false sense of security that their business models are sustainable without technological evolution.

This program is a proof of concept that SOPA will not help prevent piracy. The program, implemented as a Firefox extension, simply contacts offshore domain name resolution services to obtain the IP address for any desired website, and accesses those websites directly via IP. Similar offshore resolution services will eventually maintain their own cache of websites, without blacklisting, in order to meet the demand created by SOPA.

If SOPA is implemented, thousands of similar and more innovative programs and services will sprout up to provide access to the websites that people frequent. SOPA is a mistake. It does not even technically help solve the underlying problem, as this software illustrates. What it will do is give undue leverage to predatory organizations, cripple innocent third party websites, severely dampen digital innovation and negatively impact the integrity and security of the Internet.

Please bring this to the attention of congressmen responsible for voting on SOPA. SOPA will not technically achieve its stated objectives. Anyone voting in favor of it is morally responsible for destroying the freedoms, innovation, hard work and aspirations of many.

HOW TO USE
– Enable the Status/Add-on bar if it is not enabled (View->Toolbars->Add-on bar)
– Click on the light blue DeSopa button in the Status/Add-on bar, at the bottom of the browser window, to access websites by IP.
– Click the green DeSopa button to switch back to DNS resolution.

KNOWN LIMITATIONS
– Can only resolve tabs one at a time.
– First time resolution is a bit slow because three services are checked serially and compared. This may be done in parallel in the future, or a trusted single source may be used.

HOW IT WORKS
When turned on, DeSopa intercepts URLs, sends the base URL to three offshore DNS services via HTTP, makes a best effort to check that two of them are equivalent, caches the IP for the browser session, redirects to the equivalent URL using the IP, and substitutes out the domain name in the source code with the IP address for future requests.
