CIDR block notation question

[babadoctor]

Hello

 

I was looking at CIDR blocks on the internet, and I noticed that when people talk about ip ranges, they use CIDR notation to notate the subnet they are referring to

 

So for example:

 

192.168.1.1/24 is equivalent to 192.168.1.1-255 

192.168.1.1/16 is equivalent to 192.168.1-255.1-255

and so forth.

 

Where can i learn the endings? What are these called? Where can I find the equivalencies? 

 

(I want to know the CIDR notation for the subnet 192.x-255.x-255.x-255)

Google subnet calculator.

 

/8 /16 /24 are the most common, but you will see others. Just use a calculator for that like this one http://jodies.de/ipcalc
