Don’t use on work LAN

This story will be a turning point for my blog future starting with a change in writing methods and changing those methods to a more causal fashion.


Flame VirusFor now all my text here where somehow depersonalized and tech oriented in a way that it was all written like in some book. User manual to me concise. Maybe this is the main reason that now when I got back to revise some parts of the texts there was an impression that those text are very boring. There is something missing inside them, maybe me?
Of course, I didn’t start to write this blog two years ago because there was a huge need for someone new to write about old networking stories about protocols and networking standards. I did start to write because I was young enthusiastic freshy networker who was in his all day job searching, part-time Cisco teaching and CCNP studying period.
That was actually not job free time for me, but it was intense and fulfilling time. Having some experience with web before and now spending whole days with my head inside Cisco Press books it was somehow natural to start a blog. Yes I know, everybody wants to write something on the web, but that is the main reason for this post, I you wondered what is this all about. I can now finally say that if I did not give up writing this blog until now then it’s the real proof that there is actually somebody reading it and that I can finally consider myself a networking blogger but more that all an networking geek. Jup, that’s right, there are people who are not ashamed of being geeky technicians.

IP Address – Internet Protocol address: Basic about IPv4

An IP address (Internet Protocol address) is actually a numerical tag that is assigned to each participating device over the network either a computer or a printer. These devices are attached via networking using internet protocols for their communication.

Two main functions of an IP address are given under:

  1. Identifying a host or a network interface
  2. allocating addresses

IPv6 addresses – What is IPv6?

IPv6 addresses – what is this all about?What is IPv6 – IPv6 addresses – what is this all about? Why we need IPv6 addresses? What is this buzz all about? When the IP protocol and addressing technology first came out, there was not even close so many devices in the world that could connect to the Internet. It was hard to imagine that we will have the need to make IP addresses longer that 32-bit. So we make them 32-bit addresses and call them IPv4 address. We were not able to imagine that we will have close to 4,294,967,296 devices online? This number is simple 232 = 4,294,967,296 that means the number of different IP addresses that we can generate with 32 digits (bit) number.
