Re: They do allow opt-out like the others

[web page opt-out could work for those who set "automatically get DNS addresses" but]

For those of us who specify IPs, a web page opt-out wouldn't work.

why wouldn't it??

A web page can't change your TCP/IP settings (maybe excepting some Active-X badware, if you allow it) or anything in your router (apart from some criminal hacking techniques). And this is a good thing; a browser shouldn't have access to system settings. If your device is configured to send DNS requests to xxx.xxx.xxx.xxx:53, there's no way the ISP could re-configure it to send them to yyy.yyy.yyy.yyy:53 instead.

On the other hand if it's configured to send the DNS requests to a generic address where they will be passed on to a DNS server the ISP's device selects (that's the "automatically select" option in OS or router settings), a web request could tell the ISP to put your MAC on a list of those which get their DNS requests sent to the un-borked nameserver instead of the borked one.

What I was getting at is the very page you are redirected to should have the ability for the customer to either 1) opt out there. or 2) click to log into the page that you make the change [or get] more info on how to opt out

Yes, that would be the least they could do. They probably don't because more people would opt out. Making it something you have to hunt for on their website maximizes the ad audience.

 It has to be doing it based on mac-address without re-assigning anything. I get opted out at the DNS server almost instantly. Doing nslookup in a shell loop directly against the server the answer changes real-time as I opt-in/opt-out of the service. This behavior is very different than my previous Charter experience, which there was no freakin way to shut off.
