Re: subnetting confusion

Thanks for the reply.
What I want to do is get a better understanding of when and why changing a
subnet mask is or is not necessary. I am looking possibly at a better way
to organize my network, which is relatively small. Would there be any
benefits of doing something like (other than organization) assigning
printers on IP address ranges of 192.168.1.x and computers in registration
department 192.168.2.x and computers in finance department 192.168.3.x and
so on.
For your example you are keeping the default subnet mask. So you are saying
that without a router a computer with an IP address of 192.168.1.1 can not
communicate with a computer having an IP address of 192.168.2.1 even if the
subnet masks are the same?
Maybe my confusion lays in the fact that there are always several ways to
accomplish the same thing.
Change subnet mask if you want to accomplish (like running out of IP
addresses) this, this, or this.
Just change IP address (as in your example) if you want to do this, this or
this.
Use superscope if you want to do this, this or this.
Or do a combination of all of the above.
just trying to get a grasp on the big picture really.
