Forwarding applies, a catch-all entry specified in both sections will be considered a duplicate zone. Multiple Amazon VPCs in a single region can use an Unbound DNS server across an Amazon VPC peering connection, which allows Amazon VPC to host Unbound as a shared service with other Amazon VPCs. They advise that servers should, # be configured to limit DNS messages sent over UDP to a size that will not, # trigger fragmentation on typical network links. Pi-hole itself will routinely check reverse lookups for known local IPs. This action allows recursive and nonrecursive access from hosts within
Conditional forwarding: how does it work.
