Spectrum is still doing it (N Pinellas Co FL). Not sure if it can be turned off.

That's quite the aggressive reaction. ;)

Windstream in Ohio does it.

I'm pretty sure I had a previous ISP that did it too, but I can't remember which one now.

T-Mobile does it and that is an enormous ISP.

Verizon Fios

Time Warner (Now Spectrum) in Texas does this on residential as well as "business class"

Cox does. And I think Kabletown does, too.

> I've yet to see this on any ISP I've used anywhere, sans free airport wifis. Travelled pretty much every continent on earth.

I guess you've never been to Turkey.

Time Warner/Spectrum, the largest provider in NYC (and the only one that services my apt building) does this. They let you turn it off in your account settings, but it doesn't actually turn it off.

CenturyLink, major telecom in 37 US states. DNS requests for all nonexistent domains go to a server that delivers a dumb "search" page to web requests. They're currently the sole fiber-to-the-home provider in my neighborhood, and Comcast is the only broadband alternative.

I live near Toronto Canada and Rogers my ISP hijack's DNS requests for non existent domains. The data to back up my bold statement is a simple Google search which reveals that they have been doing this at the very least from my Google search was from 2008.

It is possible to turn off this feature, But it is set by a cookie and once that cookie is deleted you have to do it all over again.

Comcast has been on-and-off about doing it. They've switched between proper NXDOMAIN and hijacking it a few times.

I don't have Comcast anymore (not even available in my area), I can't tell you if it's current practice.

AT&T does it on their home Internet service. Annoys me to no end.

EDIT: lots of ISPs do it, in fact: https://en.wikipedia.org/wiki/DNS_hijacking#Manipulation_by_...

TalkTalk in the UK. last chance I got to test it was about a year ago.
