A subnet mask is a 32-bit number used in IP networking to divide an IP address into network and host portions. This division is crucial for routing traffic within and between networks. The subnet mask works in tandem with the IP address to identify which part of the address refers to the network and which part refers to the host. This distinction allows for efficient IP address allocation and routing.
For example, in the IP address 192.168.1.10 with a subnet mask of 255.255.255.0, the first three octets (192.168.1) represent the network portion, while the last octet (10) identifies the specific host within that network.

A subnet mask helps identify network vs. host parts!

Yeah, I agree with A. It’s definitely not about encryption or routing priorities, but I can't recall the exact details.
DO
Dona

I’m a bit confused; I thought subnet masks were more about routing than just separating network and host segments.
JI
Jimmie

I remember practicing a question like this, and I think option A is correct because it defines which part of the IP address is the network.
MA

I think the subnet mask helps in distinguishing the network and host segments, but I'm not entirely sure if that's the only purpose.
