Wtf is a subnet prefix length? It’s the number that decides how many IPs your network can have.
/24 = 256 IPs (but really 254)
/16 = way more than you’ll ever need at home
You care because if you set it too small, you run out of IPs. Too big, and you’re wasting space.
Most people never need to change it. But if you’re curious, [this video](https://www.youtube.com/watch?v=YdprN_CFVOo) explains it without the jargon.
