Odd NS setting for `g.ntpns.org`

Server operators
1

So [a--i].ntpns.org are the authoritative servers for pool.ntp.org (dig ns pool.ntp.org)

Each server of [a--i].ntpns.org has no NS record associated with it, which is OK.
Except for g.ntpns.org.

To illustrate that for a.ntpns.org:

$dig ns a.ntpns.org

For g.ntpns.org, in turn:

dig ns g.ntpns.org

g.ntpns.org.            43200   IN      NS      e.ntpns.org.

This is not per se a configuration error, it is simply an inconsistency. Maybe it is intentional, just want to see if folks are aware of this

yeah, it’s intentional. A handful of the dns servers are particularly regional, so they’re “behind” the g.ntpns.org name which will return a different IP when queried from some regions.

I wish I understood this, but I don’t :thinking:
