Re: Single domain two IP subnets

No, if they are four subnets then a router with (at least) 3 NICs
is required.

Why not VLANs? I admit this isn't my strongest area, but I thought that
was one thing VLANs could do... I bow to your expertise.


A VLAN switch is a form of (configuarable) router.

Each individual VLAN is effectively on a separate NIC;
VLAN switches include the ability to DEFINE by the admin
which ports are BRIDGED (same VLAN) and which are
ROUTED (different VLAN and different broadcast domain).

A VLAN Switch is essentially a "routed group of bridges"
but all contained within one box and configurable in software.

Please help me i needed to finish this tasks ASAP.

Chances are it is an attempt for us to do your homework.

Again, what's the ultimate goal here?

Homework is my bet.

Hi All,

I have a single Domain DC and DNS is on same server
Server name = DC.domain.com = 192.168.1.5

The users are divided in to four IP subnets:


Subnet A - 192.168.1.1-62
Subnet B - 192.168.1.65-126
Subnet C - 192.168.1.129-190
Subnet D - 192.168.1.193-254

Those are not different subnets - they're different IP address
'ranges' in the same 192.168.1.0 one.

Lanwench MIGHT not be incorrect on this one, since
those are probably subnets based on a 255.255.255.192
subnet mask.

Yep - you're right. I saw that in someone else's reply as well. Would've
been helpful if the OP had included the subnet mask.


What's the actual business/technical goal here? Knowing that might
help someone give you good advice.


I have to finish following tasks:

Task1: All the domain machines need to communicate with each other
accept Subnet C

Presuming that C were actually a subnet, what is it supposed to have
*in* it, and what's its purpose?

It sounds like a homework or (very STUPID) test prep question.

<g>



And it makes no sense for Subnet C to be part of the domain
and NOT communicate.

Task2: DNS and DC will be on Subnet A

Not an issue, even which makes it sound even more
like some homework or test prep question:

Just put a router in between with 3 NICs and have all
the machines use it as default gateway.

Why 3 NIC in the router? No point in even connecting Subnet
C if it is NOT going to communicate. <GRIN>

If you're going to have multiple subnets, you probably ought to have
a DC & DNS & DHCP server in each subnet.

There is no particular reason for recommending this. Neither
DCs NOR DNS are required on a per subnet basis, unless WAN
lines are involved.

One might expect a second DC and DNS in a real life scenario
though -- merely for fault tolerance.

Yes, and I was presuming a real-life scenario, I guess.


Task3: How il routing happen?

No routing is required with the description you've provided, but if
you were going to set up separate subnets, you could use routers, or
switches configured with VLANs.





Thanks
CK
