<p>IIRC a couple of years ago, a few services admitted to doing this to protect their customers by utilising malware domain blocklists forcing NXDOMAIN on lookups to known phishers and so on, a good move, one I do locally and have done so for many years now (non public networks though), but I'd have no problem with it being done or doing it on public networks if it meant stopping the average punter being ripped off, or their machines infected with nasties - sadly though, there may be providers who block/redirect 53 for less than moral reasons, and THAT I strongly oppose.</p>
<p><span style="font-size: 12px;">In the end DNS is DNS, the cool factor of using says google public DNS or the like shouldnt come into it, since the queried servers should return the same information - unless it prevents access to malicious content as above, and it should only ever then NXDOMAIN it, or redirect to say an RPZ type block information notice saying why its a prohibited domain - it should NEVER be redirected to another working (competitors/preferred) host/domain, or for spook purposes.</span></p>

<pre>FWIW - From the Telstra 4G network (telstra.wap APN), I can query any DNS server I like.
I would expect that that any ISP who did filter queries to external DNS would be so deluged with support calls they would end up turning it of pretty quickly.

Hi
Not sure on the state of affairs in Aus, do we have common carrier laws or something like net neutrality. Is it legal for Telstra to limit you to their DNS servers and then potentially filter out what they don't want you to browse to, does that also leave them open to being sued if people get to places they shouldn't ?

make scripts to switch off DNS settings when using telstra. So Telstra is providing a filtered internet service then? I'm not sure I could live with that. Serge On 5 March 2015 at 14:31, Ben Cooper <<a href="mailto:ben@zeno.io">ben@zeno.io</a>> wrote:</blockquote>
