IPv4 addresses are almost exhausted
According to IANA, after the allocation of four IPv4 address blocks to Regional Internet Registries on November 30, only about 3% of address blocks remained available.
Active allocation of addresses is taking place for new devices connecting to the Internet, as well as for the growing number of domain names, the number of which currently exceeds 202 million.
The last IPv4 addresses will be exhausted in September 2011.
