As already mentioned, the IPV6
uses 128bit addresses and therefore has 2128 numbers of IP
possible, ie:
340282366920938463463374607431768211456 possible combinations.
(340 undecilhões 282 decilhões 366 nonilhões 920 octillions 938 setillions 463 sextilhões 463 quintillions 374 quatrilhões 607 trillion 431 billion 768 million 211 thousand 456 )
As the IPV4
uses 32bit addresses and has 232 numbers of IP
possible, which corresponds to:
4294967296 possible combinations
(4 billion 294 million 967 thousand 296)
I mean, it’s a very, very, very high number.
Whereas in the model IPV4
we have something similar to this:
192.168.0.1
4 groups up to 3 decimal digits.
Therefore, for each set of 3 digits we have:
28 * 28 * 28 * 28 = 232
for 28 = 256.
232 = 4294967296
In the IPV6
we have the IP
in this way:
2001:0db8:85a3:08d3:1319:8a2e:0370:7344
Eight groups of 4 hexadecimal digits.
This difference in notation made possible a crease greater possibilities, which can be calculated in this way:
(216 * 216 * 216 * 216 * 216 * 216 * 216 * 216) = 2128
as the hexadecimal digits comprise 16 values from 0 to 9 and from A to F then, 2128 corresponds to 340282366920938463463374607431768211456 already mentioned.
With a simple rule of 3 we have to:
2128 = 100%
232 = x2128x = 232
x = 232 / 2128
x = 1/79228162514264337593543950336
That is, theIPV6
is 79.228.162.514.264.337.593.543.950.336% greater than theIPV4
And theIPV4
possesses:1.2621774483536188658765704452457967477130296174436807... 10-29% of the addresses of
IPV6

Free translation of Wikipedia content in English:
Ipv6 uses 128-bit addresses, allowing 2128 or 3.4 1038 addresses, i.e., more than 7.9 1028 times more than Ipv4.
This means, as the comments posted below by @Vargas and @tsippert:
Whereas the values of @bfavaretto are correct then, IPV6 is 79,000,000,000,000,000,000,000,000,000% higher than IPV4.
@Vargas Boa, I didn’t have the patience to count zeros when typing :)
I updated the value, my previous calculation was wrong ;)
When I saw IPV4 and 0000...% Li IPVA
@Tony If the IPVA were so cheap it would be good.

IPV4 has 32 bits, IPV6 has 128 bits.
It is such an absurdly large value that it is possible to say that IPV4 = 0% of IPV6

This is the correct answer, my round 79.228...
