In this post, we present an example of an IPv6 network operation, based on a home network setup that is a PC (Windows) and a box (an internet box provided by an ISP that supports IPv6). Introduction In the first paragraphs, we talk about some general motivations to use IPv6 instead of IPv4. Then, we…
This post is part of a series of posts about dynamic routing protocols and especially RIP. We’ll try to get a deep understanding of its operation and function as an introductory to dynamic routing logic in general. You’ll see that what we think easy may hide an incrementing complexity… A little introduction Before we start…
In this blog, let’s check options to enable DNS protection using meraki and integration with cisco secure connect (or Umbrella) First of all… First of all let’s recall how DNS protection works in CsC or Cisco Umbrella. To be protected a DNS request must reach the dns.sse.cisco.com that can resolve to this IP address for…...

In this post, let’s recall what is subnetting for routing and switching purposes and how it is done. Motivation Network subnetting is very important subject that maybe referred to as VLSM for variable length subnetting. The basic idea is about managing a space of IP addresses (IPv4). Historically, a network length or space was fixed…...

In this blog, let’s build a procedure, using open source tools, to secure like a cyber security professional an example of network, a home network, simple as that! Introduction Definitely, a home network like it sounds looks easy : a small router that gives access to internet with basic features, a local area network with…...

In this post, we present the work entirely accessible at link: Bézier Curves Based Novel Calibration Technique of Beamformers in IEEE 802.11 WLAN Networks, about a new way of doing beamforming in the wlan unified (WLC-based) network. Let’s recall that beamforming is the mean by which an access point (AP) concentrate the electromagnetic energy toward…
