inject_hotmail.com writes "Bell Canada started hijacking non-existent domains (in the same manner as Rogers), redirecting NX-response queries to themselves, of course. Before opting-out, you get their wonderfully self-promoting and self-serving search page. When you 'opt-out,' your browser receives a cookie (isn't that nice) that tells them that you don't want the search page. It will still use their broken DNS server's non-NX response, but it will show a 'Domain Not Found' mock-up page that they (I surmise) tailor to your browser-agent string. During the opt-out process, they claim to be interested in feedback, but provide no method on that page (or any other page within the 'domainnotfound.ca' site) to contact them with complaints. They note that opting-in is 'recommended' (!), and that 'In order for opt-out to work properly, you need to accept a "cookie" indicating that you have opted out of this service. If you use a program that removes cookies, you will have to repeat this opt-out process when the cookie is deleted. The cookie placed on your computer will contain the site name: "www.domainnotfound.ca."' Unfortunately most Bell Internet users won't understand the difference between their true NX domain response, and Bell's injected NX response."
