Subnetting allows you to create multiple logical networks that exist within a single Class A, B, or C network. If you do not subnet, you are only able to use one network from your Class A, B, or C network, which is unrealistic.
Each data link on a network must have a unique network ID, with every node on that link being a member of the same network. If you break a major network (Class A, B, or C) into smaller subnetworks, it allows you to create a network of interconnecting subnetworks. Each data link on this network would then have a unique network/subnetwork ID. Any device, or gateway, that connects n networks/subnetworks has n distinct IP addresses, one for each network / subnetwork that it interconnects.
In order to subnet a network, extend the natural mask with some of the bits from the host ID portion of the address in order to create a subnetwork ID.
An IP address is an address used in order to uniquely identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask. The 32 binary bits are broken into four octets (1 octet = 8 bits). Each octet is converted to decimal and separated by a period (dot). For this reason, an IP address is said to be expressed in dotted decimal format (for example, 172.16.81.100). The value in each octet ranges from 0 to 255 decimal, or 00000000 - 11111111 binary.
Here is how binary octets convert to decimal: The right most bit, or least significant bit, of an octet holds a value of 20. The bit just to the left of that holds a value of 2^1. This continues until the left-most bit, or most significant bit, which holds a value of 2^7.

This is a practical IPv4 subnetting lab.
Now this is a practical lab helping you test and verify your knowledge of IPv4 subnetting. We’re not simply going to talk about the theory of IPv4 subnetting. You need to subnet but in addition, configure the network and get it working. You need to configure IP addresses on routers, on switches and on DHCP servers. And then you need to configure the DHCP servers to allocate IP addresses to the clients in the correct subnet.
So once again, this is a practical demonstration and lab of IPv4 subnetting.

hackers-just-log-in!!
So many hacks happening today because of leaked credentials. No need to do something technical when you can just login. Hackers have realized that it's easier to just log in rather than hack.

Learn Python programming with GNS3. In this series of videos I will show you how you can quickly and easily program Cisco networks using Python. In this video we program a Cisco IOSvL2 switch with VLANs by using Python on an Ubuntu Docker container.
Script on GitHub:
https://github.com/davidbombal/pythonvideos/commit/98ab87bbbe3594e0105fca15060b5c9060d7c9cf
Transcription:
This is one of multiple videos teaching you network programmability using Python and GNS3.
Now that we've been able to automate the configuration of both a Cisco IOSv router and an IOSv Layer 2 switch, we'll now configure multiple switches at the same time.
So I'll drag 4 additional switches to the topology and we'll connect them to the first IOSv switch.
So this is acting as a management network for let's say a core and access layer. So these core switches will be connected to one another and they will be connected to the access switches.
So perhaps something like this. Now what you're going to remember is, these links between switch1 and the rest of the switches in the topology is an out-of-band management network,
these links between the switches would be the network used for user traffic.
Now we could delete these links to the access layer, for now I'm going to leave them there but in a subsequent video we'll use an in-band management VLAN rather than a dedicated link…….
So I'll start up these switches. One of the parts that's going to take the longest is configuring the IP addresses and other information on the switches. I'll open up a console to the devices in the topology.
So the switches are currently booting up. While we're waiting for all the switches
to boot up, let's have a look at our Python script. The first thing I'm going to do is copy script2.py to scripty3.py and then we'll use nano to edit script3.
So this is what the script currently looks like.
In the previous video I showed you how to use a range to configure VLANs on a single switch.Now what's great about using Python directly is you can test things. So if I say range 10 notice it gives me a range from 0 to 9 there are 10 values in the range.
If I say range 74 notice it gives me a range from 0 to 73.
So if I say range 10 again it's in the range 0 to 9. But if I specify 2, 10 that's in the range from 2 to 9. So if I specify 5, 10 that's 5 to 9. If I actually want to use numbers like 5, 6, 7, 8, 9, 10, then I need to specify 11.
So that's something to remember when you create a loops using the range.
In the previous video we wanted to create a VLANs 2 to 100. S
