What is a IP Address Subnet?
An IP subnet (short for sub network) is a logical division of an IP network.
It helps organize devices into smaller, more manageable groups.
Think of it like this:
An IP Address Network is like a city. A subnet is like a neighborhood within that city.
Devices in the same subnet can communicate directly without going through the router.
What is a Subnet Mask?
A subnet mask tells your computer which part of an IP address identifies the network and which part identifies the host (the individual device).
