Web hijacking by router - a new method of advertisement by Belkin

May be they simply flag your router to not redirect to any web site, but the
router still goes every x hours to their site to verify the current redirect
status of your product. This wouldn't require admin privileges on your box
to be done... but could make every router with such firmware DoS'able; just
blackhole the Belkin site and every such request would need to timeout
before the router resumes normal behaviour.
