VLSM Subnetting help

[JennisJennis]

Hello, I would like some help for this VLSM subnetting. Classless subnetting I still haven't gotten down yet, but classful is easy enough since you use the same sub mask.

So it gives me an IP: 192.168.1.0/24

and it gives me 2 hosts: Router 2: 30 hosts and Router 1: 14 hosts but it doesn't mention how many hosts the wan has or the switch etc.

from these info I have to somehow find out the ip addresses in packet tracer so i can connect the different routers/pcs/switches/wan and on paper I have to write down the subnet nr, network ID, Custom netmask, broadcast

here is the assignment: https://assignment.itslearning.com/Annotations/AnnotationApp.aspx?AnnotationAccessArea=1&AnnotationOfUserId=0&IsReadOnly=True&LearningObjectId=312684248&LearningObjectInstanceId=445241713&MobileBrowser=NotDefined&SourceUniqueId=08ee56c9-381b-47ce-a10...

and i've linked my packet tracer too. I really need help with this.

Hello,

I'll have a look at the Packet Tracer file...

Basically, for two hosts, you need a /30 mask, e.g.:

192.168.1.0/30 --> gives you two usable host IP addresses, 192.168.1.1 and 192.168.1.2

For 14 host addresses, you need a /28 mask, e.g.:

192.168.2.0/28 --> this will give you 14 hosts (192.168.2.1 - 192.168.2.14)

There are various tools available on the Internet that help with VLSM, such as the one linked below:

I already have the CIDR's. The one with 30 hosts has a sub mask of 27 and the 14 hosts has a sub mask of 28. It's just the rest i can't seem to figure out

Hello, 

I have attached the revised file. The PC config tabs are locked, you need to configure the below:

PC1

IP Address: 192.168.1.62
Subnet Mask: 255.255.255.224
Default Gateway: 192.168.1.33

PC2

IP Address: 192.168.1.14
Subnet Mask: 255.255.255.240
Default Gateway: 192.168.1.1

thank you, but how do you do the subnetting parts? the subnet nr. The network ID. the custom netmask and the broadcast. What do I write in those columns?
