Less than 10 percent of all IPv4 addresses remain available .More exactly there are only 7.8 percent of all IPv4 addresses available all over the world .
The first region affected by the shortage of IPv4 addresses is the Asia-Pacific region .On 4 February,IANA (the Internet Assigned Numbers Authority) delivered the last five blocks of IPv4 addresses in this region .The same situation is seen all across Europe .The Regional Internet Registry for Europe has IPv4 addresses for only one year .
That's why many registries started to prepare for IPV6 integration .The new protocol will allocate more than 340 sextillions new addresses .
