What are Subnet Mask and Gateway exactly
- by Saif Bechan
I have a dedicated server with multiple IP adresses. I run them on Plesk but some of the names are confusing me.
One ip has a subnet mask of 225.225.225.192, another has 225.225.225.0. What does this mean and what happens if i change that.
Another thing i got a gateway. What is that and when will that come in handy.
Another thing I see sometimes behind the ip's is /number. For example:
200.20.20.20/24
200.20.20.20/16
200.20.20.20/8
What will these numbers say.
