IPv4 address space filling up
I have a digital subscription to Electronic Design Europe Digital and they lead with scaremongering. The IPv4 address space is filling up.
The Organisation for Economic Co-operation and Development (OECD) has established that 3.65 billion of the 4.3 billion available addresses are already allocated to Internet users. This organisation believes that within three years, the world will have exhausted its stock of IP addresses.
This is something which has been known for years, if it wasn’t for such techniques such as NAT (Network Address Translation) we’d be over the edge already.
One of the issues, as stated in the article, is that the lack of IP numbers brings an additional problem there is little space left for the coexistence of IPv4 and IPv6. The address translation requires IPv6 and IPv4 addresses to be linked, in a method similar to NAT.
Besides from this there are many more advantages to IPv6, security and efficiency.
