You can have a thousand IPs and it won't matter so long as you configure your named.conf to use a specific IP in notify-source and transfer-source.

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. -- Jonathan _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users Proud partner.
