We've been watching ISPs deploy DNS redirection services (ISPs using mistyped URLS to make a buck) for some time, with some carriers doing a better job than others -- specifically when it comes to the quality of their opt-out processes. As we noted on Tuesday, Comcast is only the latest ISP to adopt the technology, nationally deploying their "domain helper service" this week.

While these services aren't particularly liked by 'Net "purists" and are largely a money grab, at least Comcast's going about the money grab the right way. We've seen ISPs so blinded by the potential new revenue of these services, they never stopped to measure how annoying the opt-out process was -- or if it even worked at all.

Not only is the carrier answering user questions in our forums about the service, we noticed last night they're offering this list of clean DNS servers for users who want nothing to do with the service. That's a nice change from ISPs who simply use cookies to opt-users out of such systems. No ISP we've seen has bothered to make the service an "opt in" affair, which isn't particularly surprising.

Given that ISPs seem to be employing these services whether customers like it or not, Comcast says they're working to standardize the use of the technology across carriers. Comcast says they've filed this IETF draft to help solidify best practices for the implementation of DNS redirection services, which is about as above board as we've seen an ISP get in terms of deploying a solution to a "problem" nobody wanted fixed.
