if you've ever been interested in boosting your internet speeds without
paying extra for it um yes
please you may have seen that changing your DNS settings can help but what the
heck does DNS mean and what kind of DNS
can actually make your browser noticeably faster DNS stands for domain
name system and it's a crucial part of how the web functions the primary job of
DNS is to take the host name of a website say youtube.com and translate it
into a numerical address called an IP address that tells your computer what
server it needs to connect to in order to load that web page if you remember
paper phone books it's a little bit like how those would translate the name of a
person or business into a phone number you could call to reach them or maybe
you weren't born in the 20th century I I don't know when you type in the name of
a website or even just click a link your system sends a DNS query to determine
the correct IP address but but this process takes time meaning a slow
connection to a DNS server can result in delays before the page loads which we
refer to as latency but here's the thing these days most major internet service
providers default to DNS servers that are pretty fast although it's still
possible to save time by changing to a faster DNS server if you're noticing
frequent problems with loading websites it's likely that this won't make much of
a perceptible difference if you're only saving 10 or 20 milliseconds so does
this mean that ad viice telling you to adjust your DNS is mostly
useless not so fast we'll tell you how it can still significantly improve your
browsing experience right after we thank the sponsor of this video delete me your

privacy toolkit instead of trying to shave off a few milliseconds of latency
by changing to a commonly recommended public DNS like cloudflare or Google
what might be more impactful is switching to a filtering DNS service
that blocks ads you see when you load a web page with ads you aren't just making
one DNS request for the actual website you're visiting
instead your system has to send lots of DNS requests because the ads on that
page often live on completely different domains not only does this add more
latency since you're making additional requests but loading all these ads can
seriously slow down your browser's performance even if they aren't that
large in terms of file size modern ads often involve lots of scripts basically
extra code your browser has to run which can make your browser feel sluggish or
even nonresponsive and have even worse consequences if the script contains
malware this is a big part of the reason that some web pages on smartphones can
be very frustrating to scroll through not only do all those ads take up a lot
of screen real estate but your phone's CPU can have a hard time keeping up with
all those scripts and this can be an issue on lower-end PCS as well a
filtering DNS service can mitigate this problem by blocking DNS requests to
known advertising servers so none of these scripts or other junk from ads
makes it to your PC or phone in the first place wait a sec we already have
ad blocking extensions and app so why would I want to use a filtering DNS well
one advantage you might want to consider is that because all you have to do to
use a filtering DNS is change a setting in your operating system or on your
router there isn't any software overhead lightening the load on your CPU reducing
battery consumption and decreasing the possibility of software bugs and if
we're talking specifically about a phone or a laptop assigning a filtering DNS
will protect you no matter where you take it instead of having it rely on on
whichever DNS server your cellular provider or a random public Wi-Fi
network uses we're going to link an article in the video description giving
you instructions on how to change your DNS server don't worry it's not hard as
well as a list of ad blocking DNS Services you can try out for yourself
one thing to keep in mind though is that unlike ad blocking extensions filtering
DNS Services can't clean up the web page for you after blocking Those ads so
you'll just see a blank space where the ad was supposed to go leaving you
wondering what kind of marvelous product you're missing out on hearing about what
if it was cool what if I wanted it hey that was a techwiki thanks for watching
if you like this video check out our other video on how Chrome is crippling
ad blocking extensions possibly making ad blocking DNS even more appealing what
a great recommendation
