I completely watched this series of 8 video on NAT, trying to understand everything and taking tons of notes. I found the explanations excellent and very clear. Thank you. I had to resort to RUclips because of how superficially the book on networking I'm reading explained this very important topic (the book is CompTIA Network+ Certification All-in-One Exam Guide, Eighth Edition, by Mike Meyers and Scott Jerningan). Fortunately, I found these videos and this RUclips channel, which will be my first reference on networking learning from now onwards. I found the pictures and the animations on the videos super useful, and I understand how much time it takes to create such good content. Thanks again.
How does the Router know where to send the packet after it arrives? Its destination is a public ip but the devices have private ips which are not defined in the packet.
The Private IPs will need to be in the Router(s) "behind" the NAT device. And the Public IPs will need to be in the Router(s) in front of the NAT device (i.e., on the Internet). More details on how Router's use the Routing Table here: ruclips.net/video/AzXys5kxpAM/видео.html
Thank you sir for this amazing video, then if i understand well this video the number of Public Ip in the world 4.2 billions adress is the same number of the router or big router ( of the internet provvider ) who existe in the world ?? if the system change from Ipv4 to Ipv6 the NAT disappear because we will don't need for it ?? thank you in advance
Not exactly, but I can see how you may think that. There are places where multiple Routers are advertising the same IP space, and other places where Routers are performing additional "layers" of NAT (known as Carrier Grade NAT, or CGNAT). There are yet other places where Routers are only routing internal address space (meaning, there could be an infinite number of those). To that end, it's probably not reliable to infer the number of Routers from the number of available IP addresses. In IPv6, NAT disappears because there are more IPv6 addresses than atoms on earth. So there will never be a need to "conserve" IPv6 address space.

Your videos are our hope to become a networking engineer, Please do not stop.
I don't intend to! You should drop by our discord: pracnet.net/discord
Thank you for sharing another wonderful series about NAT, these videos are extremely helpful , simple & easy to understand!!
Thank you, Surender =)
Hello, don't be tired
Thank you very much for explaining everything in an easy, simple and understandable way
I'm really enjoying these classes.
Next video in the series just released =)

You are doing amazing job. Keep going Buddy.
Thanks again, Mr. K!
Excellent course!! 👈👈
Thanks, Mr. D =)
Thanks so much, you made it so easy to understand.
Glad you enjoyed it, Rafay!
Yaah... It's really Very Good & easily understandable Video for newcomer. 🙏
Glad you enjoyed it, Kush =)
Exactly what I needed ❤
Your productions are evergreen. Thanks.
Thanks Azza. =)
Hi, I am a big fan of your videos. They are simple to understand.
Just wondering if someday you make a video on NAT Traversal

THIS IS A WELL EXPLANAIED VIDEOA
Thank you =). Hope you think the rest of the series are equally well put together:

@@PracticalNetworking I understand, thank you for your explanation :)
Excellent!
Very good video.
Brother u were stutter haha, by the way thanks for the amazing video.
Nice video!
Seems like a lot of addresses set aside for NAT. Wonder why they are so scattered. 192, 10, and 172 seem like very odd choices)
Is NAT used to replace DNS server? Thanks
No, not typically. Those are separate concepts that are sometimes used together.
Thank you sir
You're welcome again, Priyanka . =)
Great video!
Glad you enjoyed it
👍👍👍
The whole 127.0.0.0/8 used exclusively for localhost connections also not to forget
Creating video about NAT and not showing how translation actually works is crazy
What does this mean? He’s got like 10 videos in this series on NAT
