Hello,
My second nameserver has tow IPs, for example,
61.144.56.1
61.144.57.1
(They are in different CIDRs.)
and my ns2.example.com was pointed to these two IPs.
Will this cause problems, for example, the duplicated notification or
zone-transfer?
I would expect duplicate notifications, but that's not any problem at all.
The zone would transfer once, because a serial number check is always
done before the transfer. If a second notification was received, a
second serial number check (via SOA record) would be done, and, when
it found the same serial number, BIND would not transfer same zone a
second time.
As Torinthiel said though: try it out, and watch your logs to see
happens specifically.
