How many ips are left

Here we are in and that pool has finally run dry. Many companies, such as Verizon Wireless and Comcast , started setting themselves up to use IPv6 years ago, so as the web world transitions into its next iteration, they'll be able to get their customers online using either protocol.

IPv6 won't replace IPv4; they'll run in tandem. But companies that haven't prepared could be in for a shock. They could have to rejigger their networks, setting up shared IP addresses in order to bring on new customers.

Some may have to buy excess addresses from other companies for big bucks on secondary markets. And some may find they're simply unable to take on new business -- wireless carriers won't be able to provide web-enabled smartphones, ISPs will have to turn away people looking to add broadband, web hosting companies won't be able to build your new site -- until they're configured for IPv6.

I'm very excited we are moving on to do more things that we can't even imagine today. It is just an amazing thing. The remaining The current status of the total IPv4 address space is indicated in Figure 1. Figure 1 - Address Pool Status.

Figure 2 - Address allocations to RIRs. Figure 3 - Address Pools by State. Figure 5 - IPv4 Address Status. The cumulative number of assigned addresses over time is shown in Figure 8.

Each RIR allocates from its locally administered number pool. The pool size within each RIR over time can be derived from the allocation and assignment series data, producing the following graph.

This is indicated in Figure The next data set is total span of address space advertised in the BGP routing table over time. Of the over 4 billion IP addresses, 1,,, are allocated to the United States , the highest number of any country.

This comes out to about 4, IP addresses per 1, people. These comprise about China has the second-highest number of IP addresses of ,,, about 7. China is followed by Japan with ,, and the United Kingdom with ,, Germany has the fifth-highest number of IP addresses with ,, Vatican City , which has the smallest population of any sovereign state of fewer than 1, people, has 17, IP addresses.

This equates to 21, IP addresses per 1, people.
