‫So as I mentioned before.
‫The IPv4 address is a 32 bit number.
‫Which allows us to address maximum of two to the power of 32 devices.
‫In theory.
‫That means there are fewer than 4.3 million addresses available.
‫See where I'm going with it.
‫It's a problem because there are many, many, many, many, many, many more than four billion internet
‫connected devices in the world desktop and laptop computers, smartphones, smart TVs, smart cars,
‫even smart fridges, smart ovens.
‫You know, the Internet of Things.
‫It's the future baby.
‫This has led to a shortage of IPv4 addresses.
‫So my friend and fellow genius, what is the solution to the problem?
‫I think the long term solution is to switch to Internet Protocol version six, IPv6.
‫IPv6 has trillions of trillions of addresses enough to give every computer in the world a unique IP
‫address.
‫We'll get into that detail very soon.
‫But the most important ever to migrate the IPv4 shortage is using network address translation NAT,
‫which allows a private network to use one public IP address and that permit lots of private addresses
‫in the private network.
‫But wait, a second.
‫Wait, wait, wait.
‫Private network.
‫Nat, what that guy talking about now?
‫I thought you wanted to go to IPv6.
‫Let me explain.
