Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The NTP pool is a dynamic collection of networked computers that volunteer to provide highly accurate time via the Network Time Protocol to clients worldwide. The machines that are "in the pool" are part of the pool.ntp.org domain as well as of several subdomains divided by geographical zone and are distributed to NTP clients via round robin DNS. Work is being done to make the geographic zone selection unnecessary, via customized authoritative DNS servers that utilize geolocation software. As of October 2009, the pool consists of about 1850 active time servers. Because of the decentralization of this project accurate statistics on the number of clients cannot be obtained, but according to the project's website the pool provides time to "two to six millions of systems around the world". Because of client growth the project is in perpetual need of more servers.
