The difference here is that RFC 2308 uses "forwarder" to mean the target of forwarded queries, whereas RFC 5625 is talking about the process of forwarding queries. The RFC 2308 usage matches how you configure BIND to forward queries: you use a "forwarders" clause to configure the target servers. The problem with the RFC 2308 usage is that the nominated server is just a recursive server: the fact that you are forwarding queries to it implies nothing about its configuration. It might do iterative resolution; it might forward queries again. If you look at RFC 2308 you will see that whenever it uses the term, it is talking about other servers that are the target of queries forwarded by the server under discussion. I suggest defining "forwarding" and "forwarder" separately. forwarding: The process of sending a recursive query (RD=1) to another server (a "forwarder") to resolve a recursive query received by this server. (As opposed to using iterative resolution.) Forwarding is a function of a DNS resolver (as opposed to simple relaying done by a DNS proxy). forwarder: [RFC 2308 definition] Tony. -- f.anthony.n.finch <d...@dotat.at> http://dotat.at/ Fisher, German Bight: Northwest 5 to 7, perhaps gale 8 later.
