All a dedicated time server does is provide accurate time. An existing network server (e.g. a file server) can become a time server with additional software. The NTP homepage provides a free and widely used reference implementation of the NTP server and client for many popular operating systems. The other choice is a dedicated time server device.
The more time servers there are in the pool, the lower the resource demand on each member. Joining the pool requires at least a broadband connection to the Internet, a static IP address, and accurate time from another source (for example, another NTP server, a DCF77 receiver, a WWVB receiver, or a GPS disciplined oscillator).
For servers on stratum 2 and below, the refid is an encoded form of the upstream time server's IP address. For IPv4, this is simply the 32-bit address; for IPv6, it would be the first 32 bits of the MD5 hash of the source address.
IP addresses are assigned to a host either dynamically as they join the network, or persistently by configuration of the host hardware or software. Persistent configuration is also known as using a static IP address. In contrast, when a computer's IP address is assigned each time it restarts, this is known as using a dynamic IP address.
IEEE Reverse Address and Port Translation (RAPT or RAT) allows a host whose real IP address changes from time to time to remain reachable as a server via a fixed home IP address. [16] Cisco's RAPT implementation is PAT or NAT overloading and maps multiple private IP addresses to a single public IP address. Multiple addresses can be mapped to a ...
