Hi,
It looks like ntp-4.1.80.r1 screws up IPv6 refid's internally.
If you look at the appended ntpq output, you will see that:
- sanne.nlnetlabs.nl sync's with the IPv6 address from
"bohr.nlnetlabs.nl" (2001:7b8:206:1:240:f4ff:fe37:8232,
but truncated to "2001:7b8:206:1:" on the ntpq -pn output).
- However, "ntpq -crv" tells us that the refid=210.172.193.153.
This looks like an ipv4 number, but it is really bogus.
- Looking at another host (in this case open.nlnetlabs.nl)
we also see that sanne.nlnetlabs.nl seems to have this
bogus refid.
