Linux Magazine<p>From the latest Linux Update newsletter: Marcin Gąstół looks at the Unbound DNS resolver, which offers comprehensive security and many other useful features<br><a href="https://www.linux-magazine.com/Issues/2025/293/Unbound-DNS-Resolver?utm_source=mlm" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">linux-magazine.com/Issues/2025</span><span class="invisible">/293/Unbound-DNS-Resolver?utm_source=mlm</span></a><br><a href="https://fosstodon.org/tags/DNS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DNS</span></a> <a href="https://fosstodon.org/tags/security" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>security</span></a> <a href="https://fosstodon.org/tags/resolver" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>resolver</span></a> <a href="https://fosstodon.org/tags/DNSSEC" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DNSSEC</span></a> <a href="https://fosstodon.org/tags/Unbound" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Unbound</span></a> <a href="https://fosstodon.org/tags/Linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Linux</span></a> <a href="https://fosstodon.org/tags/DataCenter" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DataCenter</span></a> <a href="https://fosstodon.org/tags/cloud" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cloud</span></a></p>
Matt Gauger<p>Unbound is the one day of the year I want updates on the weather in Emporia, Kansas and keep trying to find live race coverage. Don’t really care about much else as far as bike racing. <a href="https://mastodon.xyz/tags/bikes" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>bikes</span></a> <a href="https://mastodon.xyz/tags/gravel" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>gravel</span></a> <a href="https://mastodon.xyz/tags/unbound" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>unbound</span></a></p>

Their website says they're a “validating, recursive, caching DNS resolver”. What does that give you over using PiHole as your DNS server?</p>
