Determining the IP address in Windows Server 2003

Here's the situation: We're running a Windows Server 2003
with IIS &  
ASP installed. IP's are assigned via DHCP.

I'm poised to buy access to a database for use in the
library and  
request a trial. Agreeing to my request, my vendor requests
an IP  
range to authenticate our school network.

I email my IT Team requesting same. [Here's where I get
confused]  
They come into the library and explain all I need do is
bring up a C: 
 prompt, run IPConfig All, cut and paste the results into
an email  
and send it back to my vendor.

Long story short, this does not get me access to the trial
database.  
I'm thinking there is another way. I'm thinking there must
be an IP  
range assigned by our ISP that we plug into our DHCP
setting. When I  
take this thought to our IT Team I'm told they don't know
what I'm  
referring to.

My question then is: What are our unknowns here?

They didn't answer your question :-( That will give you the
IP address
of the particular computer. The vendor wants CIDR[1] for
your schools
network. You can make an educated guess by using your subnet
mask as a
starting point but you are better off asking your network
administrator
for the specifics.

If you are NAT(ed) then you will just need to provide the
Vendor with
the NAT's address.

That will tell you the IP address of the server and the
subnet mask of the 
subnet it is on.  That might not be the same as the subnet
that your 
client machines are on - depends on how your local network
is structured. 
Here for example we've got two of what used to be called
Class B networks 
in the pre-CIDR days, which are subnetted into a couple of
hundred subnets 
of varying sizes.  In our case, the subnet some random
server lives in is 
almost guaranteed to be different from the subnet a staff or
student or 
visitor's PC is in, so the "ipconfig all" trick
wouldn't be much use 
here for finding the campus IP address ranges.  YMMV of
course as this is 
very dependent on how your LAN is set up.

Having this many addresses can sometimes blow the mind of 
database vendors who have on occasion been surprised when
passed 
131.231.0.0/16 and 158.125.0.0/16 as the ranges to use!  Its
much easier 
to give them the /16s though than all the myriad subnets
that these are 
broken into.

You need to ask your IT staff if they're doing NAT in any
way, shape 
or form.  If they are things are more interesting because
the IP addresses 
that your servers and clients have locally will not
necessarily be the 
same as the IP address that the remote database will see
(depending on 
how the remote database is testing the IP address).  You may
also have 
issues if you've got a proxy cache between your LAN and the
Internet 
(either configured directly in the browser, using autoconfig
or a network 
level transparent cache).  We often have to make certain web
based 
database that rely on IP addresses bypass the campus cache
as they can 
screw up sessions, authentication, etc.  That's usually the
sign of poorly 
written web front end in my experience though.

If possible put your network folk and the database vendor in
direct touch 
with one another so that they can hash out what it is they
need to supply 
to each other.

I wish vendors wouldn't rely on IP addresses as means of 
authentication/authorisation as they so often break things
for one reason 
or another.

Greetings,

You come across externally as: 125.142.218.142
So, it seems likely that your IP address range would
be 125.142.218.1  to  125.142.218.255  unless you
were sending e-mail from another location.
