What mask is optimal for an enterprise with more than 300 hosts?

Question

Computer networks

There is a network at the enterprise, in one branch 192.168.0.0, 192.168.1.0 in another 192.168.10.0, everything is combined through a router. Mask 255.255.255.0.
The total number of hosts is over 300 and will continue to grow.
Share, is it possible to make a mask 255.255.0.0 to simplify network interaction and will this not lead to an increase in network load?
How did you solve such problems?

Answer 1

Share if it is possible to make a mask 255.255.0.0

It is possible, but why?

to simplify networking

I do not quite understand how, in your opinion, and what it should simplify. You didn't specify which applications use your network and how.

Will this lead to an increase in the load on the network?

One "subnet", in general - one L2-domain, the more hosts there are, the more likely there are surprises associated with multicast and broadcast traffic.

How did you solve such problems?

If it is possible to connect different departments/branches using routing (i.e. so that they are on different "subnets"), then this, in my opinion, is the preferred way.

Answer 2

192.168.0.0 255.255. 254.0 192.168.0.0=>192.168.1.255

Answer 3

Branches connected how? Channel how much? 2/4/10 Mbps
I think you don't really need broadcast traffic in WAN channels.
