<div>Ordinarily, I agree, but the overall security and protection
of the network must come first, the protection of teh majority
must come first. Then there's the law, in Australia we are
required as part of the outcome of the iinet V hollywood, to
block pirate sites, 99% do this by DNS, the Federal court
accepts this method, the Federal court knows it can be avoided
by most 8yos in under 10 seconds, its the sweet spot everybody
agreed to so they approved it.</div>
<div> </div>
<div>There are also other laws that require its use as well. That
said we dont block any ports and have no intention of.</div>
<div> </div>
<p>That said, DoH is fairly pointless here because there is no
requirement to log DNS queries, most of us have far better
things to do than to know who's going where, none that I know do
it, though there is a question of Telstra mobile</p>
<p>lets face it, if we really want to know whos going where,
netflow tells us a whole lot more anyway</p>

I agree, if you really want to be anonymous the only way I know is
TOR. Maybe there should be a way to get DNS through TOR?<br>
