Use private address space

[PietroPoliseno27977]

Hi everyone I have a doubt in a corporate network can I use networks from 192.168.0.0 to 192.168.255.255 instead of creating subnets given a network id of 192.168.2.0/24? From what rfc defines the networks from 192.168.0.0 to 192.168.255.255 are private, that is, it is not clear to me what is the meaning of the networks, they are still private.

For example:

I want 200 networks for 200 hosts each. The book gives me an example with a class b address 172.16.0.0 uses a mask 255.255.255.0 I do not see anything wrong but considering that I can also use the third octet in private networks I can also achieve the same result ( 200 subnets with each 200 hosts) with 192.168.0.0/24 I don't see any difference

Yes, still Private.  although default is /24, you can use /16 with 192.168.0.x.  Range  192.168.0.1 to 192.168.255.254

Mostly we follow Private ranges default mask and classes but you can do whatever you wish with Private range.  I think it depends on how bit your organization is and how many networks you will have. 

10.0.0.0/8 which is used the most in all small to large corporations 'cause of flexibility in subnetting to mach your network

172.16.0.0 /12 is also good;

192.168.0.x /24 is good for small networks; small testing labs;
