I think this is a valid point. DNS is not synonymous with the Internet; neither is operations.
Internal DNS servers exist, and with guidance concerning the need for network segmentation there should be a lot more of them. I have had several requests and inquiries over the past few years specifically concerning a desire to log the addresses of clients making requests.
These requests persistently refuse to accept that DNS is an application level protocol, and that a request (or response) is recast by every nameserver it passes through even if it is merely "forwarding": "there must be a way!" People go to great lengths, there's a lot of language lawyering and playing with EDNS involved in these attempts.
Invariably my answer (for all but the most technical questions) is install a real DNS server with visibility inside of the NAT horizon (if there is one; there usually is), and that the general-purpose "logging" solution is Dnstap.
My admittedly cynical response to the question posed here is that the most common server software is probably a lightweight forwarder (e.g. dnsmasq) or something which only coincidentally does DNS (e.g. Active Directory).
