Subnetting in one network

Wed Dec 18, 2019 11:49 am

Hi everyone,

I have some question on subnet network as I have read about it on net.

They said subnet is make our network secure and good network perfomance.

EX:
I have Network: 10.10.10.0/24
1. 2 servers I subnet 10.10.10.0/26 => Netmask: 255.255.255.192
2. 25 client I subnet 10.10.10.64/27 => Netmask: 255.255.255.224
3. Ground floor I subnet 10.10.10.96/27 => Netmask: 255.255.255.224

If I design as like above in my network is really help on performance, security, and braodcast domain?
Number 2,3 need to access servers subnet then we need to route (MKT has defualt route) then it still can prevent broadcast if it still can access each other?

The mentioned security and performance benefits mostly come from breaking up broadcast domains.
Will you notice measurable, "performance" benefit, probably not, but you will limit where broadcasts will be sent with this approach.
If you are interested in securing your network, for starters, please have a look at this, as security is quite broad topic.

I thinks OPs network is too small to be concerned about broadcasts, etc. Splitting up is just going to add unnecessary complication, and if you asking that type of questions, then I suspect the knowledge is not there yet, rather just KISS

Hey. Yes, splitting /24 network will help with trashy broadcast and security issues from other hosts. After that you may need some custom firewall rules to operate traffic properly.

I suggest you answer your own homework questions. They = your university course professor??
