What is IPv6?

IPv6 is a data transfer protocol on the Internet, aside from IPv4.

It was developed to replace IPv4 due to the fact that the capacity of IPv4 has exhausted itself. In just a few years there will be no free external, not local, IP addresses.

A number of registrars do not provide IPv4 addresses already.

IPv6 addresses are displayed as eight four-digit hexadecimal numbers (that is, groups of up to four characters), separated by a colon.

An example of such an address is 2001: db8: 12: 1: 3c5e: 7354: 0: 5db1

It’s known that only 4,294,967,296 addresses of the IPv4 standard could ever be created, while for the IPv6 standard, the number of addresses can reach 3.4 times 1038.

This is a very large number; to better understand it, just imagine - if each atom on our planet is assigned an Ipv6 address - there would be enough addresses left for a hundred more planets.

In general, using the IPv6 addresses is not much different than using IPv4 for ordinary Internet users.

So why doesn’t the protocol gain popularity, why is it that its propagation speed remains so low?

The thing is that it is necessary to replace a large number of expensive switching equipment, a thing that global Internet operators not yet rush to do.
