Dear #LazyWeb,
What's the difference between 192.168.1.100 and
192.168.1.100/24 ?

I know what an internal IP address, such as in the first example is, but I'm not sure what the whole "/24" thing is about... 🤔

#networking #lan #selfhosting
/24 is the subnetwork.
It means that the first 24 bit of a ipv4 are the subnetwork, while the remaning 8 bit are for the host, it's equivalent to write "255.255.255.0" .
So "192.168.1.100/24" is a host with ip "192.168.1.100" and subnetwork "255.255.255.0"
