Global IPv4 address depletion official

Important Message:

Just 2019/11/25 UTC + 1 15:35, the message from the European RIPE NCC's been confirmed: the global IPv4 address has been completely exhausted.

IPv4 we should be very familiar with, is what we usually know the IP address, such as: 192.168.1.168 .

In fact, many years ago saying that use IPv4 over, but did not think this day actually come so early, can only say that development of the Internet really fast.

For the problem of IPv4 address exhaustion, we do not worry, the world already has begun distribution of IPv6, including China, according to incomplete statistics, China now has more than 300 million IPv6 addresses, ranking first in the world.

So in the end is what IPv6, IPv4 and so what difference does it make?

Namely IPv6: Internet Protocol Version 6, the sixth generation Internet protocol, which is developed to solve problems and deal with IPv4 will soon be exhausted, after all, a limited number of IPv4, the Internet has developed so fast in the foreseeable future, not ... ... it has now run out.

So, their biggest difference is the number.

The maximum number of IPv4 network addresses is: 2 ^ 32 (32), or less than 4.3 billion addresses, IPv6 can be up to 2 ^ 128 (128), specifically how many have lost count of the need to use scientific expression to express, but you can know is that in the foreseeable future is sufficient.

In addition, IPv6 and the IPv4 format and composition are also considerable differences, said so much, long-sawed in the end?

Look at the following addresses, IPv6 addresses are exemplary:

ABCD:EF01:2345:6789:ABCD:EF01:2345:6789 2001:0DB8:0000:0023:0008:0800:200C:417A 
2001:DB8:0:23:8:800:200C:417A 
FF01:0:0:0:0:0:0:1101 
FF01::1101 
::1

Do you feel watching, this is what the Ghosts. .

IPv6 have to say too complicated, IPv4 has been hard to remember, so behind only the DNS, domain name has been addressed, you can find the corresponding IP server through the domain name, because the domain name easy to remember than IP, more image of.

And now let's just look at the collapse of IPv6, address length to longer forms of expression more and more complex, it is convenient to be able to write down is not realistic.

即使如此,我相信,随着互联网的快速发展,这些都会随着解决的,或者有更好的处理方式。毕竟 IPv6 是趋势了,因为 IPv4 已经耗尽了。
