I only know the basics of networking, so I’ve been wondering why this “DNS-sinkhole” fubctionality can’t simply be implemented directly in private routers as a simple blocklist instead of adding a new device to your network. Do routers not support this for technical or security reasons?
Self-Hosting a DNS Sinkhole is really important

Routers are usually hardware level optimized for throughput, filtering is inherently computationally expensive compared to routing, especially if you have to keep up multi-gigabit throughput
You could totally do it at the router, it would just become a more expensive piece of hardware and most people choose to cheap out

The last time I opened the Wired site was like 10 years ago, it’s still telling me “You’ve read your last free article.” See you in 2036 ig

I guessed that an Israeli company would be behind this, and I was right. Am I antisemite?

“You’ve read your last free article.”
Do they know how ominous that sounds? It reads like they got mad at my freeloading and sent out a hitman.

You’ve read your last free article. We suggest going to the doctor for a full workup. Screen for everything. Get a will drawn up. Hug your kids.

Tells me that too. Then I copy the url into my readeck instance and it pulls the article for me and gives me a better reading experience.
Reannlegge@lemmy.ca 23 hours ago
Wow they gave you a time to come back, they have just said I have surpassed my 5 free articles for years now, I think it is because I am using a “DNS sink hole”/adblocker I do not care enough to turn my pihole off just to try and read it.
I have gotten a static IP, and clear my cache regularly since my last attempt to read a wired article so it is not that they are using anything to see that I have tried them before.

Na I have regular DNS and I can’t read from wired for years too

Unbound on OPNsense ftw
Imaginary_Stand4909@lemmy.blahaj.zone 1 hour ago
I love Unbound bro. Gives a neat list of the noisest domains which I can quickly add to my list if I don’t need that site 😌

What is a DNS sinkhole and how is it related to the content of the article? Didn’t seem to mention DNS
chagall@lemmy.world 19 hours ago
What is a DNS sinkhole
A DNS sinkhole is a little program that sits in between your computer and the DNS server that provides your internet lookups. It looks at all of your DNS requests in an unencrypted format. If a DNS lookup from your browser, mobile app or any other internet connected machine matches an entry it has in its “blocklist” then it returns a value of
0.0.0.0(or some other customizable value includingNXDOMAIN). But if the DNS entry is not on the blocklist, then that request will be forwarded to Cloudflare (1.1.1.1), Google (8.8.8.8), Quad9 (9.9.9.9) or other DNS provider and get an accurate value for the DNS lookup.Most of the time, the blocklists consist of adware domains such as Google Ad Services, Facebook Ads, Amazon Ads, etc. This has the effect of removing ads from devices that normally are unable to block ads such as ads inside mobile apps, ads in Roku, etc.
how is it related to the content of the article?
The article indicated that the malicious spyware was transmitted through viewable ads on the target’s mobile device. This is combated most effectively by using a DNS sinkhole.
I should note that the article does not mention if current blocklists would have thwarted this attack. However, it does say that the ads were transmitted, in some instances, via Google Ad services, which these blocklists do effectively target.

This sounds like AdGuard Home is an example?

I like technitium. Way better than pi hole.
lIlIlIlIlIlIl@lemmy.world 22 hours ago
In what way(s)?
bigmclargehuge@lemmy.zip 22 hours ago
It’s a more complete dns server. You can more easily do dns over https, set up zones, and custom dns entries are a lot easier imo.
In summary it’s more focused on being dns, the ad blocking is a feature on top. You also don’t have to manually configure unbound for recursive dns like you do pi hole. Etc etc
EncryptKeeper@lemmy.world 15 hours ago
The main way is it has a built in recursive DNS server so you don’t have to duct tape Pi Hole and Ubound together
kmartburrito@lemmy.world 19 hours ago
This is the way

I have a finally tuned pihole that offers different blocking for different vLANs on my home network and VPNs, I would not trust a third party for ad blocking. However you do you.
I was watching SomeOrdanryGamers video on this and his pihole did not block all the ads on an ad infected site, but mine could. I have used canyoublockit many times to stress test my system, wish there was something newer though.
lemmylump@lemmy.world 20 hours ago
Trust it, no.
Is it better than nothing yes.
Listen, some folks can afford to build and dedicate time and resources to making a pi-hole for their network.
Those who can’t need to know there are alternatives, some are better than others, I’m just sharing information.
Seimhe@lemmy.world 23 hours ago
Thanks for the tip. I can’t find pricing on the NextDNS site. Is it free?
Don’t think I have the spoons for things like PiHole.
GenderNeutralBro@lemmy.sdf.org 23 hours ago
It’s free for a limited number of queries per month. Generally enough for one device (depending on personal usage, obviously).
Mullvad has a free ad-blocking DNS you can use, too. I recommend the “base” version: mullvad.net/en/…/dns-over-https-and-dns-over-tls

Is Adguard Home still a good option for this kind of thing?
Reannlegge@lemmy.ca 22 hours ago
Yes, from what I understand. They are using ad services from the big ad companies, and because capitalism sucks they are completely fine with selling the spots.
if you do not have a system to VPN into your home I would suggest get a firewall (preferably one you can install openWRT of opnSense on) and VPN into your LAN when away from home.
jsnfwlr@lemmy.ml 18 hours ago
My TPlink omada router has Wireguard built in, so I use WG tunnels on my mobile devices to tunnel home where my PiHole (soon to be replaced by Technitium) blocks ads and malicious content.
