Sorry, please ignore me, I made a mistake. I see this sort of thing:

Feb  9 08:49:09 chacha pdns[29964]: Received NOTIFY for example.com from 
2001:db8:1f1:f019::2 which is not a master
Feb  9 08:49:09 chacha pdns[29964]: 1 slave domain needs checking, 0 queued for 
AXFR
Feb  9 08:49:09 chacha pdns[29964]: Received serial number updates for 1 zones, 
had 0 timeouts

So in fact I was getting distracted by the specific mention of
2001:db8:1f1:f019::2 and was not paying attention to the "1 slave
domain needs checking, 0 queued for AXFR" which I am now thinking is
pdns correctly responding to an UPDATE that it got from the IPv4
address it accepts as master.

It's too early, and I'm trying to diagnose an unrelated problem!

Cheers,
Andy
