This is not really connected to DNS, but URL monitoring and manipulation.
If you attempt to use the following URL:
You will be redirected to Rogers.Search.Com
The DNS services do not actually resolve URL addresses, only the domain names to IP addresses. What Rogers is doing is far worse. They are actually reviewing what addresses we are browsing and manipulating the results.
If you remove the "&src=IE-Address" from the sample URL above your results will be returned normally. This is further evidence of this blatent abuse of service.
