On your webserver:
Set some IPs in your subnet to your NIC. Say your main IP address for the
machine is If you add some IPs to that same NIC in your
IIS4 machine, you can assign each one of them to a particular website.
In IIS 4, your main website "" would be assigned to
You could then assign to ""... --> ""... --> "" (subdomain)
In DNS, you'll have a primary zone for each of your virtually hosted
domains. So in the examples above, you'd have something like:
Primary zones:
[somename] (subdomain of -- not a primary zone)

For each primary zone, you'd have various DNS records like
[] A
somename A
[] A
[] A

You'd have to add NS, MX and any other CNAMEs or A records to each primary
zone as needed. Do not add an NS record for a subdomain
( toplevel domain is already handling that
with its NS record.
