The IPv4 has been around for more than 30 years, it was a solution provided for some research and military group. It became more and more popular until today that there are only 0,78% of the available addresses left. Yes, we are talking about only five /8 blocks of the IPv4. And according to the rules this 5 blocks will automatically be allocated to the five RIR:s (Regional Internet Registrar). This means practically within some month there would not be any IPv4 left. No no no , no reason for rushing for Ipv4 addresses because you can allocate IPv6 addresses as almost unlimited resource (at least as far as we can anticipate today ;-)).
It’s is time to say goodbye to IPv4 and welcome to it’s true successor the IPv6. Either you are with us in the future and fast track or you may be left behind. There are lots of new possibilities for invention, business case, new technology in front of you to catch.
