Yo, subnet prefix length is like the size of your IP address pool. The /number tells you how many bits are locked in for the network part.
/24? That’s 24 bits for network, 8 for hosts. So 256 IPs.
/16? 16 bits for network, 16 for hosts. Boom, 65k IPs.
Why does it matter? Cuz if you set it wrong, devices might not talk to each other. Or you could run out of IPs.
If you’re just at home, don’t sweat it. But if you’re curious, [this guide](https://www.techopedia.com/definition/24162/subnet-mask) breaks it down nice and easy.
