Advice about IP

[pasqui83]

Hi All,

Sorry for the re-post - I just realised I put it in the wrong area.

I am trying to create a virtual server at the moment as I am learning active directory, so I have windows server 2008 and windows 7 in a virtual environment).

I am trying to learn about IP addresses and I have somewhat have a clear understanding of it (class A B C ETC... and subnets).

Currently I am with Virgin. I use a wireless router, the PC I am using is connected via Ethernet. The config on my wireless router is just basic (so I haven't changed what Virgin have put so I have internet).

When I go to create my network connection in Windows Server 2008, I want to create a class A, this is pretty much what I will have

IPV4: 10.0.2.15
Sub 255.0.0.0
Default Gateway (my virgin information)

With my preferred DNS - Would I stick to what my Ethernet Controller has at the moment or do I make my own one up? I only have 1 connectivity and that is with my Virgin and assume that is the only 1 I can use.

You have to configure whatever virtualization software you're using (vmware/virtualbox...) depending on how you'd like to have it configured.

There are a few options. If you have no need for INTERNET access from the VM then you can use the 'Host Only' style networking. Then you can set the IP/DNS to your virtual server to be whatever you want. Any subsequent virtual machines (backup virtual server, virtual client) on the same subnet will be able to communicate.(There is also probably a virtual network adapter installed on your HOST O/S that, if you configure, your host is part of that network too.

OR if you do need internet in your virtual environment then you need to select either Bridged or NAT networking. Bridged means your virtual server will VIRTUALLY literally be on your wireless router's network. You would be able to communicate with other PCs in your house (non virtual) or printers, etc...The downside is that in this configuration you need to follow the network of your router. Which is to say, you cant set the class A address you mentioned because your router is probably using the standard 192.168...

You could also do NAT if you need internet but dont want to follow the networking scheme that your wireless router uses.

So in summary the answer to what DNS address you need to use is dependant on which type of networking you have configured (NAT, bridged, host-only).

The way I always had it set up was using host-only, and the windows server itself was running DNS service (since its a domain controller), so my DNS address was just 127.0.0.1 (local).
