Greetings! I know that NTP resolves hostnames on startup and, after that, the NTP packets are exchanged with only those IP addresses.
I also understand that the NTP Pool Project design is based on this premise. The question is: how effective is the monitoring platform in removing the dead or bad (from the monitoring platform viewpoint of course) NTP servers from running NTP clients on users' computers? This was just a rhetorical question of course. The monitoring system can't notify the NTP daemon in the end users' computers. As an end user with a 24x7 powered computer I would have to check the NTP daemon once in a while. I know the chances of all 4 of the poll assigned NTP servers becoming bad are pretty remote. On the other hand, for a 24x7 computer a discerning user would probably choose 4 properly administered and maintained NTP servers close to him. I would at least. So it seems to me that the NTP Pool Project would be best targeted at computers not running 24x7 or, better, might be being used mostly by computers in these conditions. Why then isn't it possible to allow users willing to provide their bandwidth to the project to use their dynamic IP based servers to support the project? Something like a quick, say 30 minutes, convergence to a 10 score and the monitoring platform would do a DNS resolve when the server stops responding perhaps because the user changed it's IP address. Any arguments why this is not a good idea? Cheers, Miguel PS: As a side note, I have a stratum 1 at home (a Trimble Acutime Gold antenna) and use some other close by stratum 2 servers as backup. In my company I have 2 Meinberg NTP servers and 3 more GPS based custom made servers.
