How does NAT conserve IP Address Space? (and why!) – Network Address Translation
Network Address Translation, or NAT, was created to extend the life of IPv4. The world has been running out of IP addresses (for 10+ years, 🙄!). The permanent solution is to switch to IPv6. But in the mean time, we can use NAT to extend the IPv4 address space further and further.
In this lesson we’ll look at exactly how NAT extends the IPv4 address range.
This is the first video from a series of Videos where we once and for all explain NAT in an effective and practical way.
0:00 – IP Addresses
1:19 – IP Addresses are finite
2:40 – IPv6 is the long term solution
3:17 – NAT is the bridge between IPv4 and IPv6

Very good video.
Thank you ❤❤
Brother u were stutter haha, by the way thanks for the amazing video.
Exactly what I needed ❤
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
Hello, don't be tired
Thank you very much for explaining everything in an easy, simple and understandable way
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)
THIS IS A WELL EXPLANAIED VIDEOA
Your videos are our hope to become a networking engineer, Please do not stop.
Is NAT used to replace DNS server? Thanks
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.
Thank you sir
Thank you for sharing another wonderful series about NAT, these videos are extremely helpful , simple & easy to understand!!
Thanks so much, you made it so easy to understand.
Your productions are evergreen. Thanks.
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
I'm really enjoying these classes.
Yaah… It's really Very Good & easily understandable Video for newcomer. 🙏
Great video!
You are doing amazing job. Keep going Buddy.
Excellent course!! 👈👈
