NTP — Network Time Protocol

ntp.inetstat.net is an open access stratum 2 NTP server. NTP is the standard Internet protocol for high precision time synchronisation across the Internet, typically achieving 1-50ms accuracy, or better. SNTP (Simple Network Time Protocol) is a simpler subset of NTP for clients who do not require high precision, just a relatively simple time sync to the nearest second.

This service is provided for the general good of the Internet, but may be withdrawn without notice if it is abused. Please respect the spirit in which open access NTP servers are offered and realise that access to these servers is a privilege, not a right. See the rules of engagement below. Abuse will not be tolerated and abusers will be banned summarily.

Why have I reached this page?

You may have reached this page unexpectedly while looking for information on the pool.ntp.org project. The correct URL for the project web site is http://www.pool.ntp.org/. iNetStat.net is not responsible for the operation of pool.ntp.org — we merely provide a server in the pool.

Location

This server is located in Roubaix, France, on the OVH network, accepting both IPv4 and IPv6 traffic. It runs the standard ntp daemon from ntp.org, currently on version 4.2.8. It should offer reasonably good NTP performance across the EU. People outside the EU should really seek a server closer to them, as NTP precision degrades quite a bit once you are talking about trans-continental / trans-oceanic distances (it's still going to give significantly better than 1s accuracy under normal circumstances, but you'll get much better results from nearby servers, as well as avoiding inefficiently utilising the finite trans-continental and trans-oceanic resources).

Rules of Engagement

ICMP Destination Unreachable — Communication Administratively Prohibited

If you are receiving these ICMP packets (type 3, code 13), shown as "unreachable - admin prohibited filter" by tcpdump, you have been banned from this service. If you stop sending packets, the server will stop replying with these ICMP packets telling you that you are banned, and your ban might eventually be lifted. If you keep sending packets, despite being banned, your ban will probably be permanent.

If you send packets at a high rate after being banned, that constitutes network abuse, and your ISP may well notice an excessive number of these ICMP packets and choose to suspend your service! If you are observed sending packets at a high rate after being banned, your ISP may receive a complaint asking for your service to be suspended for network abuse. Additionally, your address may be published as an abusive host, or reported to various network abuse databases, which could have a negative impact on your ability to communicate with other servers.

It does not matter whether whether it is deliberate abuse, badly implemented software, or badly configured software. You are responsible for ensuring that your software does not behave in an abusive manner.

Support

iNetStat.net does not offer support for this service, or for configuring your client systems correctly. See the NTP Public Services Project for all support issues.
