Internet Protocol IPv6 has appeared in 1998 as Faqs.org states.
It will soon replace IPv4 because slowly but surely we are out of IP addresses.
The IPv4 architecture can sustain 2^32 IP addresses. This means 4.3 Billions of IP Addresses which in 2 years from now on they will be all addressed. No more addresses, no more computer networks.
An IPv4 address has 32 bits. This means you can group 8 bits in a 4 numbers from 0 to 255 like :
129.232.45.1
The IPv6 architecture which has 128 bits or 2^128 IP addresses can sustain 3.4*10^38 IP addresses. This is an enormous number comparable to the number of atoms in the Universe.
A typical address will have 8 hexadecimal numbers with 4 digits like :
2901:0db8:8fa3:0000:0020:8a2e:0370:7134
One reason that I am not agreeing with IPv6 is that it is not very efficient for a system administrator or for a network engineer to use and handle. This IP address ca be confused with a language code in Hexa or something else. It’s not usable, it’s not easy to take.
What if you should follow some traffic, make some traceroute and so on on this IPv6 address?
The second reason is that it’s to much waste of traffic and of numbers. Practically from 2^32 it has extended to 2^128 IP addresses much much more that you’ll ever need.
For internet growth whatever much it will continue to grow will very sufficient in my opinion an IPv4.2 Internet Protocol architecture with 48 bits. Very enough for the current needs and for every futuristic prediction. A typical IPv4.2 address will look like that :
134.127.0.23.45.1
practically add another 2 groups of 8 bits number making the new IPv4.2 address.
This will be enough for further development of networks without fear that we will have no longer IP addresses.
