DNS Experiment
The DNS experiment blocks all outgoing traffic over the standard DNS port (<span class="code-class-custom">53</span>), optionally constrained by supplied IP addresses. This experiment is equivalent to running a Blackhole experiment against port <span class="code-class-custom">53</span>.
Linux
This experiment does not interact with <span class="code-class-custom">iptables</span>, and so it does not interfere with any existing <span class="code-class-custom">iptables</span> rulesets.
This experiment requires the <span class="code-class-custom">NET_ADMIN</span> capability, which is enabled by default at installation time. See capabilities(7)
