very clever man!,many thank for your content.I'm currently particular in learning and practise CCNA. Hope for next few months, i can get my first CCNA cert.Thank you!
I just love you, man. Your content is fantastic. The illustrations are always helpful. And, you really seem to get granular, and include concepts that most instructors may ignore, or gloss over. Great stuff,, man. Soooo glad I found your channel while reviewing for the CCNA.
I am so glad to find you in youtube. You are the father of the teaching network in the earth planet. A request Could you do a series on DNS, how it works and how to troubleshoot related issues?
Very cool. Instantly subscribed. Thanks for making this simple. Not sure why the Cisco Network Academy tries to encrypt the information only to make it harder to understands. This seems very basic.
Hello Ed, i came to this video just because i had the same doubt regarding the interfaces the router uses to response the directed broadcast performed on a foreign host, i think it is just because this interface its the one that reaches the destination IP address of the host that sends the broadcast, i am guessing this just because in case that you do directed broadcast from r1 to r2 for example, let r2 g0/1 be the broadcast ping, and the g0/0 interface the one directly connected to r1, r2 in this case, would use its g0/0 since its directly conneected to r1. great video!
Does this demonstration only work with a hub? Because I have tried it on my L2 switch on my eve-ng lab and the ping is not going through for both the directed and the local broadcast. Any help?
Great point! You are correct, Routers don't forward broadcast messages. But the key is what makes a packet a broadcast packet. The answer is in the longer version of this video where I set up packet captures and we look at the packets in Wireshark to explain *exactly* what is going on. th-cam.com/video/ny6MsSLb8_o/w-d-xo.html
I tried pinging 255.255.255.255 on my local network but I only got a response from my own machine's IP address. The router and other devices are not responding to this ping but they respond to their respective unicast pings. why may this be happening?
Often pings to broadcast address are disabled for security reasons. More details here: www.practicalnetworking.net/stand-alone/local-broadcast-vs-directed-broadcast/#bc-security

Hi Scott. I've enjoyed seeing your comments on so many of my videos =). Glad you are getting a lot out of this content!
Your explanation to every topic is crisp and clear. I appreciate you take time out of your busy schedule and create knowledge content for us.
Thanks Kumar. I appreciate that! =)

DNS is on my list. I don't know when I will get to it, but it would be fun to teach. Glad you enjoy the content, thank you for the kind words =).

greating some where in east Africa Somalia
Thanks ! Explanation is amazing. It cleared my concept
Glad you enjoyed it!

Please make videos on various tunnels like IPsec and gre. You make things easy to understand. Thanks.
You're doing a great job! Love your videos!
Thank you =).

Thank you!
You're welcome, Nikolaos!
very good explained! :)
Thank you =)
great video 😍👍
Thank you!
Could you make a DNS record a broadcast address and would it act as an umbrella for all ip addresses?
wait but i thought router does not forward broadcast messages
