Lab 6 1: Simple Subnet Design - jude-lindale/Wiki GitHub Wiki

Summary

In this lab we were tasked with calculating new subnet masks, new subnet addresses, finding the broadcast address, and finding the available host range.

The steps I took were to look at the chart that we were given. Then I figured out the new subnet mask in CIDR Notation and the number of bits needed to get there as well as the new subnet mask in dotted-decimal. from there by looking at the chart I was able to find the new subnet addresses because the last bit of the tri-ad increased by 4. the same was done with the broadcast address but all that was needed was to subtract 1 from the last part of the tri-add of the subnet address. For the range, the first had to be one more than the host address and the last had to be one less than the broadcast address the corresponded with the initial subnet address.

Tech Journal Question

If you must support X equal-sized subnets, how many bits do you need in your subnet ID?

It depends on the number of subnets that are needed and what the starting address it
