Re: DNS redirection is NOT deep packet inspection
Awesome, thanks! I agree, there are some big names in there. More than I thought. |

So far, as best I could determine with search tools, AT&T & Comcast haven't started doing this yet.

said by drjp81 :You totally missed it. Rogers is rederecting failed DNS requests and possibly others based on the DNS names that are passed through it's customer's HTTP requests. Which means there is a discrimination of what service or protocol you are using for the DNS redirection. {they all do that. No service is redirecting non-http(s) requests} So while a ping at www.blababla.com might answer nobody's home, Rogers can hijack a HTTP request without even attempting to resolve the name. How then can you trust the content of a website? You go to wikipedia.org, Rogers detect via DPI the URL and domain name you are going to, and the redirect parts of the site with whatever content is commercially viable for them. That's the plan. But that isn't what they are doing or even what they are being accused of. They are redirecting bad domain names to their search engine and nothing else. Saying they COULD do this or COULD do that doesn't prove anything. Any business supplying DNS services COULD do many things.
Some people don't like redirecting mistaken domain names, but that is done by almost all ISPs now and also many Toolbars - Google included. Most people like the service. For those that don't - there are DNS servers out their that will just return an error when something is mistyped or when a page has an invalid link.
