Although this protocol has been around since 1996 it has been anticipated that IPv4 would one day be exhausted. In February 2011 the Internet Assigned Numbers Authority (IANA) assigned the last /8 address blocks to the Regional Internet Registries so time is getting close but you have heard this warning before right? Let’s go over IPv6 at least just an overview some the features and changes compared to IPv4 because one day it will happen it’s just a matter of when.

Password Recovery – Cisco IOS Routers
In this post I want to cover how to recover passwords on a Cisco IOS Router. This is helpful in lab environments as well as production environments. Although this method can be used the correct “legal” way you can also use this method to break into these devices “illegally” if you have physical console access to the device. However to get into it physical power must be turned off first causing a disruption in the environment, let get started! Continue reading

Part 2 – The Joys of Subnetttting – VLSM!

So let’s get started! Continue reading
Part 1 – The Joys of Subnetting!

I remember back when I started to learn subnetting it was confusing and I wanted nothing to do with it. The thing that made me change my mind was after I understood it and how important it is.

Subnetting has always had its moments with people and in this blog I’ll do my best to show you what I have done to make subnetting an easier experience. Continue reading
