Because some companies run with an effective

    iptables -t filter -A FORWARD -p udp --dport 53 -j DROP
And prevent anything from their own internal resolvers from accessing outside DNS services, especially now that encrypted SNI is moving more web filtering to the DNS layer.

But that one is OK. DNS over HTTPS doesn't exist to circumvent enterprise content filtering (hence why you can hint you don't want it to run with a DNS entry, making it vulnerable to downgrade attacks).

Easier to make the orgs internal recursive resolver "does the right thing" than all clients, too.

Replace "enterprise" with "ISP" or "nation state", and that's closer to what the DoH aims are.

Sure, if you have internal only sites, you pretty much have to, and this is used even in small and medium shops.

DOH will cause so much drama when internal sites wont resolve any more.

Its perfectly ok to let your internal sites be resolved outside your network? Abc.internal resolves to 192.168.0.101 is fine?

How do you do PTR records? (what hostname is 10.12.43.122) How do you do split DNS? (Inside my network I want it pointing to my internal server)

Now you could argue that the fault in both of those cases is IPv4 and the natting that comes with it.

i don't get the ptr problem. My internal sites already have ptr records. My dns server sits facing the internet. Ptr records too.

But yes. If u have a domain that is supposed to resolve different depending on the source ip that'd be..interesting... Now u need a website that displays different content depending on source ip or something like that...

If your machine is pointing to doh on the Internet, how does a reverse lookup for an rfc1918 address work?

One issue with doh is that it’s inconsistent - some applications use one resolver, some use another. The network (via dhcp) can’t hint at which resolver to use.

i'd prefer not to. We work for a number of different clients, and its common to have pg11-clientanme.* and node-clientname.* ...

I have over 200 domains internally, that i don't have externally.

but its also flexibility. We often when we develop, want to redirect certain domains to our endpoints, for testing or whatever, and do that on DNS so that not everyone has to edit host files etc.

we have pfsense internally, with number of people that can and do add/remove hosts/domains on daily basis, but host our external DNS on CF, and only 2 people have access to that.

What's the risk?
