Can someone tell me if this is possible?

Hi,

Can someone tell me if this is possible: I have a Windows 2000 Network with
2 domain controllers and a network address of 192.168.1.0. Can I create a
site with a Windows 2003 domain controller, ip address 192.168.2.2, or would
the ip address of the 2003 server have to be a 192.168.1.--- address?.

If the above is not possible, then is it possible to change the subnet mask
of my network from 255.255.255.0 to 255.255.0.0 to allow a greater number of
hosts, and having the network address of 192.168.0.0. Is this second
scenario possible? If the first can work, and also the second which is
better?

Thanks in advance,
Sam

Is the new box 2.2 on the same wire as the 1.0 network ? Do you want them to
talk or not ? You could change the subnet for all boxes to 255.255.0.0 and if
they are on the same wire (LAN), then you could go willy nilly with
addressing 192.168.0.1-192.168.254.254

Hi Erfert,

Yes I want everything to be on the same network. The problem is I want to
setup a remote office, I would have preferred to have everything on the
192.168.1.0 network, but I realize it was not going to be possible since my
devices would be greater than 254. So I was thinking of making the remote
office a 192.168.2.0. but I was not sure if I could have that DC on a
different network address from that of headquarters, and still have it as
part of the domain as a site. But from what you are telling me it should be
possible.

If I change the subnet mask on my 192.168.1.0 from 255.255.255.0 to
255.255.0.0, what Class would that be? The subnet mask looks like a class B,
but the Network address would start with that of a Class C. Would this be
right?

Thanks

If it is at a remote site, it will be best put in a different IP
subnet. Sites are usually joined by some form of IP routing, so they must be
in different IP subnets.

Active Directory specifically caters for sites in different IP subnets.
In AD Sites and Services you can define the IP subnet for each site. This
improves the way AD works (eg it directs hosts to use the DC in the local
site for logon, etc). AD replicates across the site link.

So your home office would be 192.168.1.0/24 and the site something like
192.168.2.0/24 .

Easy question:

when you type 192.168.1.0/24.....

does that mean all addresses within 192.168.1.0 thru 192.168.1.24?

The second scenario is possible but the best practice would be to switch all
the IP addresses to 172.16.0.0 range or 10.0.0.0 range. As someone else
mentioned if they are in two physically different sites you should probably
use different subnets. Otherwise there will be a lot of unnecessary
communications over the link between the sites.

No. 192.168.1.0/24 is a shorthand way of writing 192.168.1.0 netmask
255.255.255.0 . The 24 indicates the number of bits in the netmask.
10.0.0.0/8 is the same as 10.0.0.0 netmask 255.0.0.0 and so on.

Hi All,

I would like to thank everyone for their suggestions and responses. It was
always my intention to create a site and use subnets. But I think I need to
brush up on my subnetting skills alot more after reading your responses. In
response to Kerry Brown, I still want to maintain the 192.168.1.0 network,
and not change any of the devices on that network ip address because I do not
want to tamper with the ip addresses of the tempermental non windows servers.

Thanks
Sam

Question: Is 255.255.255.254 in essence the same thing as 255.255.255.0.
Will they both yield the same number of hosts?

Yes, you do need to brush up! You may need to write them out in binary
to see the full effect (especially if the mask is not a multiple of eight).
The ones in the netmask show how much of the address is used for the network
address. The zeros show how many hosts you can have.

For a simple example. take 10.0.0.0/8 . 8 bits covers the first octet
(ie the 10. field). So the network address is 10 and all IP addresses
starting with 10 are in this subnet. Millions of them!

At the other extreme, 192.168.1.27/32 (or 192.168.1.27 netmask
255.255.255.255) is all by itself. If you see it in a routing table, it is a
host address. It applies to that machine only.
