Have a look at this KB article (you'll need to register to view - but registration is open to all): https://kb.isc.org/article/AA-00726/30/Tuning-your-BIND-configuration-effectively-for-zone-transfers-particularly-with-many-frequently-updated-zones.html Also - and this isn't covered in that article (yet) - if you're using views, then use-alt-transfer-source defaults to 'yes'. You might want to set it explicitly to 'no' or to define alt-transfer-source and/or alt-transfer-source-v6. _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
