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
2 servers I subnet 10.10.10.0/26 => Netmask: 255.255.255.192
25 client I subnet 10.10.10.64/27 => Netmask: 255.255.255.224
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. https://wiki.mikrotik.com/wiki/Manual:Securing_Your_Router ,but keep in mind, that this article is not a complete guide for every scenario, as depending on your goals, you could also utilize for example, dot1X, bridge-filters, static-arp entries, etc.
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.
