DNS over TLS example

Since you're using the DoT FQDN of security.cloudflare-dns.com, need to change the IPv4 addresses to the corresponding 1.1.1.2 and 1.0.0.2.

I have a little note on my phone keeping track of a few public DNS resolvers. Here's what I have for Cloudflare:

Cloudflare
1.1.1.1
1.0.0.1

2606:4700:4700::1111
2606:4700:4700::1001

DoH:  https://cloudflare-dns.com/dns-query
DoH:  https://mozilla.cloudflare-dns.com/dns-query
DoT:  cloudflare-dns.com

----------------------------
Malware
1.1.1.2
1.0.0.2

2606:4700:4700::1112
2606:4700:4700::1002

DoH:  https://security.cloudflare-dns.com/dns-query
DoT:  security.cloudflare-dns.com

----------------------------
Malware + Adult
1.1.1.3
1.0.0.3

2606:4700:4700::1113
2606:4700:4700::1003

DoH:  https://family.cloudflare-dns.com/dns-query
DoT:  family.cloudflare-dns.com

I used Cloudflare DoT and DoH (in all browsers) for quite a few years but in the past year or two switched to Quad9 after a Lawrence Systems video compared a handful of public DNS resolvers' ability to block malware sites. The results showed that Quad9 blocked significantly more than Cloudflare.

Here's the listing I have for Quad9:

Quad9

9.9.9.9
149.112.112.112

2620:fe::fe
2620:fe::9

DoH:  https://dns.quad9.net/dns-query
DoT:  dns.quad9.net

The only drawback with Quad9 I've noticed compared to Cloudflare is there's no option for adult site filtering like you get with 1.1.1.3/1.0.0.3 and family.cloudflare-dns.com

For me there is another drawback, which is latency, unfortunately.

Also looks like Cloudflare's filters aren't that good...

DNS servers that come built in with anti-malware ...

What I make of that : they use a DNSBL, the one we don't have (?), the one with all the sites that host malware.
Isn't that a bit like "Use XyzVPN and you don't risk anything anymore on the net ..." ? It makes me .... sad to realize that there are really people out there that actually believe that. But also somewhat upset, as these people really don't care about there own devices (the data on it, etc) and that their actions can take down entire home networks and companies.

Ours browsers can't get any mall-ware, as they can only download html, php css and harmless other files. It us, the ones with a mouse in ours hands that give the order to download another type of file.
Because you clicked on that promising button, so the file got loaded on your system.
Then, because it was that "Free Office Microsoft 365 for Live" installer that you were looking for, you execute it ....
I'm pretty sure this always happens to the same persons.

Anyway, I've this site, www.papy-team.fr, This site isn't not used anymore, and exists for historical reasons. Google is still very active on it, crawling all over the place. The server logs tell me this.
This site, afaik, isn't blocked no-where. So I've uploaded a mild mall ware on it some 10 days ago. It's not hidden really, neither in plain sight. I'll see when 1.1.1.1 stops suggesting my own site.

1.1.1.1 scans like Google the entire Internet for bad content ?
If I find bad content, I have to call them to tell them ? Notify them ? I mean, how did they get the knowledge my site is bad ?
My, how do we call it ? "Microsoft Security center", contacts 1.1.1.1 if it flags a mall-ware somewhere ? I'm pretty sure it will call home with this info, but not 1.1.1.1.
Ok, 'Home' (Microsoft) gives .... sorry, I'm rude, sells ( !! ) this info to the most bidder, like 1.1.1.1 ?

And
So, afaik, 1.1.1.1 uses a DNSBL. Ok ...... I've already my own DNSBL.

To terminate my rant (as it is ;) ) : Glad to know that 1.1.1.1 also uses a DNSBL these days.
And yes, I know, I get it, if you have a household with kids, or run a prison, you'll be looking for solutions. What's wrong with the ancient method ?

I used to have a DNSBL list here too, but adults list are huge.
And DNSBL lists have a big impact in IO on the drives.
So, I decided that having IP lists and some geoIP lists are fine, but DNSBL would be better in my case to use a third party service.

@mcury

Thanks - that a good motive.

For example this one :

will explode a "1100" and even my "4100" has a hard time loading, storing, indexing and using it.

edit : I tried to use it again. The Xxx list, 4.5 million host names.
It loaded ... ( took 2 minutes )
Half an hours later : new events in the system logs :

Info : I'm using a 4 Gbytes RAM 4100 (and a huge drive).
The Xxx list needs way more memory - at least 6 Gbytes or so. At least a 6100 could work.

@Gertjan it makes me sick to my stomach how the adult content and malware is out there. my SG-2100 when running the full block lists in squid guard would grind the thing to a just loading them it’s unreal. Finally a simple one button setting solution for networks. It has reporting tools, testing linking, it’s simplified. It’s a gargantuan block list managed by a major dns provider, this opens up all sorts of consumer bases that want the one button simplified solutions. The fact that a major dns made a solution makes me happy

@JonathanLee I'm checking it right now.
I have dual WAN here, so I can't use general settings like you did.

Edit:
Unless I use 1.1.1.1 for one WAN and 1.0.0.1 for the other..
hmm

Edit2:
Left the gateway option empty in general settings, added both family.cloudflare-dns.com for 1.1.1.1 and 1.0.0.1, disabled DNSSEC and enabled forwarding and Use SSL/TLS for outgoing DNS Queries to Forwarding Servers.

Testing now.

I had mixed results re leaving gateway option empty, so set one to each.

JonathanLee

@mikey_s 1.1.1.2 and 1.0.0.2 you mean right they use and adapted IP. I think the company is branded as 1.1.1.1 so they still have the corporate branding and symbolism but to use the family settings if you read it they are .2 or .3.

I am wondering what software development model they used for this if it was a rational unified process, or waterfall model, incremental development, or integration and configuration? Maybe Integration and config or reuse oriented model. It kind of appeared without any advertisement that’s why I question the model. The cost of evolution of this product must be big, they just eat that? Where or how is the url black lists obtained? They had to have one ready to get to work so fast, think about all the urls you submitted to blacklist sites over the years, that database did not occur overnight.

Correct, the 1.1.1.3 and 1.0.0.3 servers.
Two WAN connections, one is 4G failover.

Originally I had both assigned to the primary WAN and Quad9 assigned to the 4G backup.

My other firewall is a Sophos XG and the failover / multi WAN setup on that is nice.

Changed, testing now.
Disabled DOT btw.

EDIT:
I'm getting around 40ms to quad9's DNS servers, but decided to test it in my network.
Using 9.9.9.11 and 149.112.112.11, each one of them assigned to a different WAN.
Using DOT: dns11.quad9.net
DNSsec enabled.

Everything seems to be working perfectly so far..
Missing the adult filter.

EDIT2:
Do you guys know if Unbound in pfSense is compiled with ECS support ?
