Doh!  I just cut and pasted from the current file, so I'll make sure that
comes out.

Am I right in understanding that everything will still resolve and mail
will work because the IPs aren't going to change?  Also, we'll still only
have a single reverse file - should that stay ''?  When we
finally get to the single domain model, we'll fix that, but that's still
about a year off, it looks like.  Any idea what might break in that time?

Thanks.  I wasn't sure what would happen to our nameservers if I started
playing around with their names.  About the shortcuts - If I use a FQDN for
something outside of Accenture, will that carry down to the next record?
Do I just need to make sure all FQDNs are at the bottom of the zone and
nothing goes after them?

Many thanks,
