What do you think is bad about it? I've been working with DNS for 20 years and this is about as straightforward an explanation of the difference as I can think of, and jibes with my understanding. Am I misinformed? <http://www.techexams.net/forums/net-infra-70-291/29238-dns-recursion-forwarding.html> says pretty much the same thing. Is this also bad information? Or how about <https://www.digitalocean.com/community/tutorials/how-to-configure-bind-as-a-caching-or-forwarding-dns-server-on-ubuntu-14-04>? What this article defines as a "caching" name server is rather the same as a recursive server, but the definition of a forwarding server is the same - basically a proxy server. Programmers don't like the use of the term "recursion" when applied to a name server, but the word has a general meaning that can be applied in a lot of contexts, some of them in a variety of IT fields. -- Lindsay Haisley | "We have met the enemy and he is us."
