The Forgotten skill of technical writing

It’s a beautiful sunny day that puts a big smile on my face and I want to share it with you, so please put a big smile on your face now and before you continue. Your smile will make my day even brighter. OK, back to our post but keep smiling 🙂 If you are reading my blog then you are related to networking one way or another, and if you are related to networking then most probably you write technical documents and this means this is for you. In our daily lives as network engineers we involve in technical …

IPv6 Tutorial: IPv6 Unicast Address

To refresh our memories, we started our IPv6 tutorial  with an overview then we moved to IPv6 addressing in general and in this post I am moving deeper into IPv6 addressing types. As promised I will keep things simple and clean for you and for me, so let’s begin. Generally speaking IPv6 unicast addresses play the same role unicast addresses used to play in IPv4 networks. There are plenty of different IPv6 unicast types this post will focus on four of them. Global unicast address: Global IPv6 unicast addresses are equivalent to the public IPv4 addresses, this means they are …

Life Follows a Plan, but the Plan is not Yours !

70 days passed since I wrote my last post about IPv6 Addressing. Long time, however I didn’t feel it. Maybe I even forgot what I was doing here or planning to do, those 70 days actually carried a lot of unplanned events. My last post was on 24th of January and on 25th of Januaray it all started with protesters in Tahrir square asking for justice and equality for all the Egyptians, that was the begining and it ended by me now writing this post from Amsterdam, Netherlands where I currently work. Those revolutionary days had a lot of lessons, …

Private IP address ranges

IPv4 Private Address Ranges:   10.0.0.0/8 IP addresses: 10.0.0.0 — 10.255.255.255. 172.16.0.0/12 IP addresses: 172.16.0.0 — 172.31.255.255. 192.168.0.0/16 IP addresses: 192.168.0.0 – 192.168.255.255   Private IPv4 internet address ranges are defined in RFC1918 with the motivation to control growth of the internet routing tables and to preserve IPv4 addresses space to extend it’s life. The private ranges defined in this RFC are not routable over the internet and are intended for internal use only in private Internets/Intranets and that means these packets destined to these ranges will not be routable across the internet and should stay within the private network. …

IPv6 Tutorial: IPv6 Addressing #1

I am back again with the second post in this series, in the first post we had an overview of IPv6 and the need for it in the near future. In this post we will start breaking the technical ice of IPv6; I am going to discuss basic IPv6 addressing. This will need more than one post to finish. My philosophy for this series will be “Cut the jargon and keep things, simple and straight as possible”. That’s why I will try to keep it short and to the point . Let us begin: IPv6 Address size and space: This …

IPv6 Tutorial: The overview

I will start from the beginning; two weeks ago I wrote a post claiming that IPv4 is depleting and IPv6 is coming soon; and since we are considering deploying IPv6 soon in our network, I thought it might be useful to write about IPv6 migration and transition strategies. Although, this is important but I think the readers of this blog including me will benefit more if we start at the beginning even if it takes longer to get where I wanted to start. I will start small and build up as we go toward the new IPv6 internet. Get yourself …
