I can see that I should have made sure of exactly what version of OpenVMS (and associated Digital TCP/IP  
software) that we are running, and, if necessary I will check with the comp.os.vms group to  
help make sure there is not some unforeseen hitch. (I suspect I will find out we need to upgrade whatever we have.)
FYI, the desire was to have a URL of dept.org.com instead of www.org.com/dept  (and dept2.org.com, center.org.com, etc.)
I think since my sys adm feels we need to set up a separate machine with it's own IP to do this,
we will need to make sure that we know exactly what to do before we touch the DNS. It's probably an  
understandable concern that we might mess up a working DNS trying to do something we don't  
fully understand. And yet, I don't think setting up separate servers for every group (and keeping them  
patched) is the best direction if DNS (and header records in IIS)  
can be used to point to multiple sites on one server.
Thanks.

The IP stack IS native in OpenVMS 7.1 and maybe earlier, but that has absolutely nothing to do with the question. The latest version that I have is VMS 6.1 where
UCX was an addon and it certainly did NOT include BIND.  In any case even the
most primitive version of BIND or any other DNS will allow you to add A records.

Adding an A record does not require a check with another new group.

If you had REALLY read the message, you would know that a) it's a woman who's
first name is Mary; b) that it wasn't a different domain; and c) it's irrelevant.
