Very informative! I appreciate your understanding that some people are just getting into this topic and taking the time to explain how the little things come into play

Thanks for the informative DNS subject material as well as being super polite

Very useful video! Seeing how this process is captured on wireshark clarified the whole process for me. Thank you.

Great way to begin the new year, congrats for continuing with the giveaways, is a good way to keep us motivated and continuing learning.

First of all I wanna thank you for all of your videos you provide a lot of valuable information to us. And I wanna ask a question that for beginner which one is better GNS3 Or EVENG to start for better understanding not for just clear the exam.

@davidbombal

Thank you. Both are good and both have advantages and disadvantages. However, if you are new to networking, I would suggest you start with Cisco Packet Tracer - free, easy to use.
