[Help] Need Guidance Configuring IP Addresses in Packet Tracer

Hi everyone,

I’m currently working on a Packet Tracer project and I’m a bit confused about how to correctly assign IP addresses. I’d really appreciate it if someone could check my understanding.

Project details:

I’ve been given the internal address space 192.168.1.0/24.

The ISP provides 1.1.1.1/24 for the WAN connection.

Subnetting is required: “192.168.1.0/24 with 3 subnets for 16 hosts per network.”

Here’s how I understood it (please correct me if I’m wrong):
I divided the 192.168.1.0/24 network into 3 subnets, assigning one to each switch:

192.168.1.0/28 → Switch 1

192.168.1.16/28 → Switch 2

192.168.1.32/28 → Switch 3

Each subnet should provide enough addresses for about 16 hosts. The subnet mask for each network would therefore be 255.255.255.240 (/28).

For the PCs connected to each switch, I plan to assign IPs within each subnet’s valid host range (e.g. 192.168.1.1–192.168.1.14, etc.).

Could someone please confirm if my subnetting and IP allocation logic is correct?
Thanks a lot for your help — I really need to get this sorted out soon!
