Perhaps I misunderstand what > you mean by "sub-domain". I'm sorry, I was imprecise. You are not allowed to create subdomains locally, they must all be registered with the .US domain administrator. An example of what I mean. I have a DECnet network (yes, I run VMS) consisting of 2 local area clusters. For unix types, this is similar to having 2 NFS servers, each with a group of satellite machines. Each of my clusters has a DECnet node alias, and a real node name. For instance, MIS1 is a workstation in one of my clusters. It can be reached with the node name MIS1 or MIS (which will refer to a random node in the cluster, but all cluster nodes share the mail repository, so this works fine). I have it set up so that tp@mis1.mccall.com is legal, and gets delivered on node MIS1. mis2.mcccall.com is the other machine in the cluster, and mis.mccall.com will go to one or the other machines. A similar scheme is used for the other cluster (which is the only way they can get mail from the outside, since mccall.com gets delivered on the MIS cluster). In otherwords, I've completely mapped my DECnet network onto my local set of subdomains. I didn't have to ask or tell anybody to do this. If I had registered in the .US domain, I'd have had to register all of these (it would add up to 12 domains). Every time I got a new workstation, I'd have to register it. My MX forwarder would have MX records for all of these, thus propagating this hassle to even more people. In the .com domain, I've registered mccall.com and also declared my node (known as mccall in the uucp maps) as the gateway to the .mccall.com domain, so that mail to tp@mis1.mccall.com gets sent to host...!mccall!mis1.mccall.com!tp, and delivered properly. One of the great benefits of domains is that you don't have to advertise your entire network to the entire world, you just advertise your domain gateways and then handle routing to subdomains internally. -- Terry Poot The McCall Pattern Company (uucp: ...!rutgers!ksuvax1!mccall!tp) 615 McCall Road (800)255-2762, in KS (913)776-4041 Manhattan, KS 66502, USA
