I just want to say that I love your videos you put things into proper prospective and provide the information with simplicity and they are easy to comprehend. You are great!

I have a dumb question. What can a person do with a single VLAN as mentioned on 01:14 ? Wouldn't that just be a LAN on its own?

[@professormesser]

A single VLAN indicates that all of the devices will be on the same broadcast domain. I mentioned that it was a single VLAN to emphasize the difference over an enterprise switch that might support many VLANs.

[@cdoremus99]

Basically means that every device on that switch is a part of the same network. On switches that can apply several VLANs and assign different ports to them like a Cisco 2960, you would need the assistance of a router to communicate with the devices that are assigned to different VLANs, even though they are connected to the same switch. TLDR is that a VLAN is just another word for Network, LAN, Broadcast Domain.... All of these words mean the same thing. You need a router (or layer 3 switch) to communicate with other VLANs/Networks.

I have a question, Why would they put a Router and a WAP in one device if both have the same fundamental functionality of supplying devices Wifi connection to the internet.

[@professormesser]

The WAP provides the wireless access, and the router forwards the packets. They actually perform two very different tasks.

[@ibnsham8357]

@@professormesser But wireless routers also provide wireless access. My understanding of WAP is the it's a device that expands wireless access in your LAN. For example, in a business a WAP can be installed in different areas to strengthen the signals and allow stronger access to the internet. but with only wireless capability, Sort of an extension a capability also found in routers. Have I misunderstood the functionality of a WAP?

[@professormesser]

A "wireless router" is a device that contains both a router and a WAP ( wireless access point). Most of those devices also include a switch, content filter, and firewall, all in a single physical device.

[@mrnobody1321]

i'm confused. can we change the ip address of our own device without getting into the routers config? what happens if that number is the same than other device on the network?

[@Lucasperks06]

we'll then it wont allow you to use that ip address.

[@haydenjones8191]

no

[@cgme7076]

Unless you have IP addresses that are statically configured (you've configured them to always use the same IP address), your router will always change your IP address when you reset it. It does this using DHCP, and it mostly used for device security. If someone knows the internal IP address of your device then they can continue attacking your device on a network. So, unless you have a DNS system on your network, you generally want to allow your router to reset IP addresses when you restart it. At least as far as I understand the process.

[@mrnobody1321]

@@cgme7076 Thanks for the answer!! How does the dns enters the play here? In any case once they use my IP, still won't be able to decrypt any data, and won't have any cookies to acccess email right away isn't it? Have a good day

[@flamemonger2]

How fickle is the end user device config when it comes to opposing IPs? Say I connect to a network and am assigned x.x.x.17 for my IP but in my connection settings I configure my ip4v manually and say my ip is x.x.x.20(unused in this case). Would the router not allow me to access the network with this IP? Would I now be leasing two IPs or is the x.17 now released from my MAC address?

[@cdoremus99]

If you statically configure the IP within your OS it will override any dynamically learned (usually through DHCP) IP address. So in this case the device would only have the x.x.x.20 IP address. You need to make sure that you configure the correct subnet mask and default gateway address. By default in a SOHO network the default gateway is usually 192.168.1.1 (or just the x.x.x.1 host) and the subnet mask is 255.255.255.0. If you're on a network and don't know what the gateway or subnet mask is just go to the command prompt and type "ipconfig /all" on windows or "ifconfig" on Linux. I don't have any experience on MAC OS so I'm not sure what the command would be for MACs, but a simple Google search will find that answer for you if you need it :)

[@roguesquadron521]

@@cdoremus99 I believe on macOS the command is also "ifconfig" as you can use the Terminal application for both macOS and Linux (if I am wrong please correct me!).

What are you connecting that’s considered to be in the WAN

[@professormesser]

On most SOHO routers, the WAN interface is for the Internet connection.
