Isn't this one of the points of Net Neutrality? My ISP (Comcast) doesn't do this currently. I suppose I'll have to check again on January 21.
I don't think this specific example is malicious (it's part of Google's Edge Network I guess? I wouldn't know), but it does show that they're already capable of modifying the DNS lookups ran by their customers.
I'm with BT and they don't appear to do this.
I suspect you maybe seeing resolution to Google's edge network. This isn't modification - it is how DNS is designed to work.
Perhaps I'll check some other domains too.
Without it the functionality described above will just work - it's only when you are using an unusual DNS setup that the extension is needed.
Actually, init7 itself is in Germany, right ? I know they have POPs there, as in France and .nl, etc.
