How many different types of subnetting questions are there?

Hello,

I'm working on the subnetting portion of the CCNA exam and there appear to be many different types of subnetting questions. I've come across:

1) Which subnet does host xxx belong to?
2) What is the last valid host on the subnetwork xxx?
3) What is the broadcast address of the network xxx yyyy?
4) How many subnets and hosts per subnet can you get from the network xxx yyy?
5) What is the first valid host on the subnetwork that the node xxx yyy belongs to?
6) Subnetting when given a required number of networks
7) Subnetting when given a required number of hosts
Given an IP address & Subnet Mask, finding original network range (reverse engineering
a subnet problem)


So are there more? I'm looking for a guideline for the different types of subnetting questions that there are.

binary, there's almost always a way to put a new spin on the questions. The secret is, learn how they work, and no matter the question type, you will not be unprepared for it.

Here are three off the top of my head--

Name three possible subnets that have the broadcast address 140.13.3.255.

Variably subnet 140.13.0.0/16, to create at least 15 subnets with 250+ hosts each, and to create at least 15 subnets with 2,500+ hosts each.

What is the last IP address on the 140.13.0.0/16 network?

Yes, us interviewers are tricky sorts.
