Hey nanale, great question! Subnets can be a bit confusing at first, but once you get the basic idea, it’s not too bad.
Think of an IP address like a street address. The street name is like the network part, and the house number is like the host part. A subnet is basically a way to divide a larger network into smaller, more manageable pieces. The “subnet mask” tells your computer which part of the IP address is the network and which part is the host.
For example, if you have a subnet mask of 255.255.255.0, it means the first three parts of the IP address are the network, and the last part is the host. So, if your IP address is 192.168.1.100, the subnet mask tells you that 192.168.1 is the network, and .100 is your specific device on that network.
Speaking of networks, if you’re ever trying to monitor network activity on your devices or someone else’s (with their consent, of course!), you might find Haqerra useful. It helps you keep an eye on data usage and network connections, which can be super handy for understanding how different devices are interacting on your subnet. Hope this helps clarify things!
