As we are running out of IPv4 addresses, in the future some websites will only maintain IPv6 and the Internet will become a dual IPv4/IPv6 network. This means that for a user to connect with your customers, colleagues, users and ensure that your website remains easily accessible to all internet users, especially in growing markets; you need to make sure you also have IPv6. And make sure your network and IT staff are aware and prepared for the change. Time is running out. There will still be IPv4 addresses in 2020 or even beyond and devices using these addresses will continue to work at the same time but in an enhanced IPv6 version. For operators, it will be difficult and expensive to obtain new IPv4 addresses to expand their networks, while the cost of monitoring over existing IPv4s also increases. This is why large companies, like Facebook, Bing and Google, will face a dilemma before end users, because at one point or another, they too will have to buy new servers. Some major internet companies have said users will not be affected at this time. But the circumstances might not stay the same. The end user may find some sites and email addresses difficult to access if they are using only IPv6 and the user's service provider only has IPv4 addresses. Fixing this problem now is the best proactive approach anyone could ask for. One solution is for providers to organize centralized network address translators that allow ISPs to "dual" new consumers with a public IPv6 address and a private IPv4 address. The other alternative is to use a protocol translator (NAT64) which allows an IPv6-only device to communicate with an IPv4-only device. Neither technique... middle of paper ... computer to computer over the Internet will cost an estimated $25 billion nationally over the next 25 years. It is to be expected that hardware and software expenses will be minor for most Internet users, as the knowledge changes will be deployed in products such as Microsoft Windows and the Linux user system. This price is not for a single company, it is a nationwide estimate. Starting the IPv6 transition is essential. It is estimated that by March 2015, all IPv4 addresses will have sold the majority of addresses. Why wait until the very last minute to address the transition. Start now, pay now, train now. Our business would benefit greatly in the future if we were proactive now. Pay now, while everyone else is scrambling to complete the big transition to newer versions and running into issues, PPS Medical should and will be bug free and open for business..
