Minor thing: the /24 does not indicate a class. Classes were abandoned in the 90s :) See CIDR (the C stands for classless). In a classful network your 10.0.0/24 would not be 'possible' as it would technically be part of one of 128 class A networks (ranging from 0/8 to 127/8). To get a /24 you would have to use 192.0.0/24 to 223.255.255/24. Yes, classes were really that silly... (I know that 10/8 was private even in classful times but it is an illustration.)

This video conflates VLANs (Layer 2) and subnetting (Layer 3). Both are valuable topics for discussion, and often go hand in hand, but it is worth distinguishing between the two. Reducing broadcast traffic is a layer 3 issue that can be solved through subnetting and using a router. VLANs are layer 2 segmentation, and are more akin to virtualization of switch hardware. You don't need VLANs to reduce broadcast traffic, you just need additional subnets on a router (or routers) with a sufficient amount of distinct ports and separate switch networks for each of those subnets. Obviously VLANs help solve the multiple ports and multiple switch networks by virtualizing all of that infrastructure on top of a single set of physical infrastructure, but VLANs are really only incidental to the reduction of broadcast domain sizes.

@darrenfalconer3267 3 жыл бұрын

So if I wanted to separate printers and computers from let's say ip phones I could use subletting rather than vlans? Does that mean say example phone son 192.168.1.x and other PC's and hardware on 192.168.10.x??

@@darrenfalconer3267 In enterprise networking, the phrase "Make a VLAN" is implying that you will be creating both a VLAN and a subnet that would be associated with that new VLAN.

They are doing two different things at two different layers, as indicated by Luc Lagarde, but they go hand-in-hand when implemented on your network.

Have to correct at 6:45 , although you're using a /24 SNM it's still a class A network since it's in the A class "block". The three private ranges are each in a seperate class btw. 10 A Class 172 B Class 192 C Class

@jmhm17 3 жыл бұрын

It's using a VLSM, and its called a classless address - that is very much a class C. The beauty of private networks is you can carve them up however you want. You can create any ip space you want you do not need to have a classfull address of 192.168.1.x to only use a /24. You can literally make any subnet a /24 but the rules of subnetting still apply to your host, and network bits. The mask is what determines your network size. Not your network address.

@beauregardslim1914 3 жыл бұрын

"Class C" actually has nothing to do with subnetting of private networks. In the olden times (before the introduction of CIDR in the mid-90s), you would request a "Class C" from the IP address registry and they would assign a publicly routeable block of 255 addresses to you. I mention this because new network admins seem to think that using /24 blocks is something to conform to, when you are probably better off using larger (or smaller) address spaces for different network setups. IPs for DHCP pools, for example, start adding up quick when you have redundant servers.

I think that within the last 10 years, we've finally seen classful networking not being taught in networking classes.

separating servers from clients can be tricky....you would then rely on the routing capacity of your router to route traffic between networks (unless you have a router on a stick configuration in which your switch is acting as a L3 switch and is doing inter-vlan routing) - this is fine if every vlan has its own physical interface, but becomes tricky if you use the same interface for many many vlans. You avoid broadcasting traffic at the expense of pushing all traffic through the same interface and saturating its bandwidth.

Love it!!! I'll do it for sure... but please, please, please, do a video on Pi-Hole as DNS and DHCP server for the main network. Just to explain my idea. Here at my home I have a total of 5 computers, 5 portable devices, 3 game consoles, 1 rack server with some virtual servers (one being the Pi-Hole DNS as you teach in the past video), I also have some IP cameras in the network a NVR device for recording the cameras and Smart TV's. Mainly, what I want to achieve here is to separate the Computers, Consoles, Devices from the cameras and some servers. My router is a TP-LINK ER-6120 and it does support VLAN and also is the main DHCP server in my network. I can also use a MikroTik Hex Rb750gr3 but I'm still studding it. My main doubt is about having access to my cameras from different VLAN's, and still have my main network protected. Also, do a video on Pi-Hole DHCP, this is very interesting.
