I'm starting trying to understand subnetting. Any help would be appreciated.
Follow me here:
- Lets say I have one public class C address from my ISP
- Lets call it 200.200.200.1
- Lets say I have 500 clients.
Why do I even need to subnet? NAT is confusing me... Can I not just have a router with NAT and then do whatever the heck I want on my LAN? (like my two home computers do).
Router WAN 200.200.200.1 ~ 255.255.255.0 Router LAN 10.0.0.0 ~ 255.0.0.0
In the above scenario I can just throw everyone on the 10.x.x.x network and be done? Do I only need to subnet when issues of bandwidth/ collisions come up? I understand all about broadcast/collision domains.. but I'm confused about how subnetting "saves address space" when you can just use NAT to split one address into a million...
My head hurts... if anyone can point me in the right direction without using any big words it would be much appreciated....
