I think you have this backwards. It looks up chealth.canoe.ca.centroid.eu first. Your browser apparently doesn't think chealth.canoe.ca is a full domain, and so it starts creating a full name and resolving that. (or not the browser, but the local dns cache. you're not clear what server you're machine is contacting.) fwiw, I only see queries to chealth.canoe.ca and not any local domain extended variants, using both both ping and firefox. on the other hand, if I ping "apple", there are lookup requests for apple.home.tedunangst.com, apple.tedunangst.com, and apple.
