For best performance and ease of management, is it better to use 192.168.x.x or 10.x.x.x range of addresses for a small (<50 PCs) business network?
This would correspond to a subnet of 255.255.0.0 and 255.0.0.0 respectively.
This is a Canonical Question about IPv4 Subnets.

How does Subnetting Work, and How do you do it by hand or in your head? Can someone explain both conceptually and with several examples? Server Fault gets lots of subnetting homework questions, so we could use an answer to point them to on Server Fault itself.
- If I have a network, how do I figure out how to split it up?
- If I am given a netmask, how do I know what the network Range is for it?
- Sometimes there is a slash followed by a number, what is that number?
- Sometimes there is a subnet mask, but also a wildcard mask, they seem like the same thing but they are different?
- Someone mentioned something about knowing binary for this?
Can anyone tell me what some of the implications of having two different subnets on the same switch would be if VLANs are not being used?
Are IP addresses with a 0 in the last octet valid?
10.6.43.0
In my case, I have the the following netmask
255.255.252.0
What about a 0 for the other octets?
Under what conditions does one start to consider subnetting a network?
I'm looking for a few general rules of thumb, or triggers based on measurable metrics that make subnetting something that should be considered.
