Recommended size of Subnet
Posted on 2014-10-25
I wonder what's the recommended size of each subnet. for instance how many hosts should be in each subnets, considering mapping Vlan to subnet.
let's say I have this network 172.16.0.0/16 that I will subnet and make it 172.16.0.0/24
This will give me 256 Subnets of 254 hosts each, and each Subnet will have it is own Broadcast address : example:
As know Best practice is to map each subnet to a specific Vlan. however I am not sure if 254 hosts in one Vlan does not impact performance.
OR do I need to subnet it further: to /25 or /26 in order to have smaller subnets ?
