I was talking about sites that have "done it wrong" (my opinion, and
probably yours too - it's just not right...) so to speak, and are
forcing port 53 traffic to different places than it was intended to go

Let's say that I have my local (desktop if you prefer) resolver (which I'll
call A is pointed to a caching nameserver B.
Caching nameserver B forwards all of it's DNS requests to their ISP's larger
caching server C.
Caching server C makes queries to the appropriate authoritative server D.
So the DNS query goes:
D replies to C with a record having TTL of 3600. C forwards request to B, B
gives answer to A ... TTL 3600.
"Proxying" would be the best phrase I could call it. Some commercial
active firewall implementations do something similar.
