I have both Wollongong supplied gateway to DECNET, and Ultrix supplied gateway to DECNET. Wollongong supplies the node.decnet and Ultrix supplies node.dnet. (This may not be a complete list, other vendors may also use those methods). As the administrator responsible for overseeing the gateway to the rest of the world from our internal network, I have attempted, and as far as I know succeeded, to excise these addresses from the mail which leaves our network and enters the outside world. >Since this is uucp we're talking about, I don't think you can say that >node.decnet or node.dnet is illegal, though I'd agree heartily that it's >ugly and disgusting. I believe this statement is wrong. I also believe that any address of the form node.transport-mechanism is wrong, including node.UUCP. However, I don't do anything active about this belief, except my best effort to insure that anything leaving my domain conforms to this requirement. Anyone dumb enough to source route through my site should succeed, but why? They can route decwrl!uunet faster than decwrl!eda!uunet 8^) >Greg Paris P.S. Someone in this thread asked about Paul Vixie. He's still at decwrl and vixie.sf.ca. (Sigh.
