CaptSolo writes "UPC Ireland has started a trial of a DNS hijacking "service", in a violation of net neutrality. When users enter a URL for a non-existing domain, they are redirected to a landing page (for example, this). They do provide instructions for disabling this service, consisting of a PDF with screenshots demonstrating how Windows users can change DNS servers.
An example log of a hijacked HTTP request: http://gist.github.com/211317
