What DNS actually is
DNS is the lookup system that turns names like
google.com into the numerical addresses devices use to connect.
That lookup runs constantly in the background for websites, apps,
smart TVs, and games. Most homes use ISP DNS by default and never
revisit the choice.
Why this matters for privacy and security
DNS requests reveal where your devices are trying to go. With a
filtered provider, many risky domains can be blocked before pages or
app content load.
What NextDNS adds
NextDNS
still does normal DNS lookup, but adds policy controls: security
blocklists, category filters, logging, and encrypted DNS.
Because this happens at the DNS layer, it can block trackers and
malicious domains across many apps, not only in your browser.
Bottom line
NextDNS
is one of the highest-impact upgrades you can make to a home network:
affordable, flexible, and effective for both family safety and personal
discipline online.
Keep the first setup simple, observe your logs for a few days, then
add stricter rules only where you consistently need them.
Personal note: NextDNS has solid documentation and setup guides, but
if you are having trouble configuring it, I am happy to help you get
it working. Email me at
