So clearly there is some list somewhere that ntp pool assigns to each country that is in each zone… For example my server is in the north american zone, and in the us.
What I am looking for is an easy cidr listing of this NA zone so I can use it to limit who can query my server. I for sure could create my own from multiple sources and can see what countries are included in the NA zone from here.
But it would be so much easier if there was already list that was available. I would think there has to be if they are creating the zones in the first place. Have to know and setup what netblocks are in these zones, etc…
A url that is updated every now and then that points to a text file with IP/cidr would be freaking fantastic
