Hey there! Welcome to DigiDev!
I made this channel because networking used to confuse the heck out of me too. I just want to explain it in a way that actually makes sense, even if you’re brand new to all this.
We’ll go over the basics like how the internet actually works, IP addresses, cables, Wi-Fi, switches, routers… stuff like that. I’ll show you simple examples, draw things out, and do easy labs so you can see it for yourself.
No fancy terms unless I explain them first. I promise to keep it relaxed and fun. New video every week or two (life gets busy sometimes, you know how it is).
If you’re just starting out in IT, curious about how networks work, or want to understand your home Wi-Fi better — you’re in the right place.
Subscribe if you want to learn with me! It really means a lot. See you in the next one! 😊

Beginner question I get a lot:
“Why can’t my phone see the printer on the same Wi-Fi?”
Answer: Some routers have “client isolation” or “AP isolation” turned on by default.
Turn it off and boom, devices can talk again.

When I first started, I thought every network needed a huge expensive router.
Turns out most home networks just use a cheap router that does NAT, DHCP, and firewall.
Anyone else thought it was all super complicated at first?

I’m thinking of doing a “Subnetting for Dummies” video.
Would you watch it?

The “no ip domain-lookup” command on a Cisco router stops it from trying to turn every typo into a DNS lookup.
Saves so much time when you fat-finger a command 😂

Switch = same network, connects devices
Router = different networks, sends traffic between them

Do you actually understand what a default gateway is?
It’s just the IP of your router so your PC knows where to send packets it doesn’t know how to reach.
So simple but can be confusing

If you ping a website and get “Request timed out” but you can still browse it, it might be because the site blocks pings on purpose

When you see “192.168.1.0/24”, the /24 just means the first 24 bits are the network part.
So the last 8 bits are for hosts (254 usable IPs).
