Hi Petr, Thanks for your reply. I was doing this because sometimes the recursive DNS has multiple IP addresses, meanwhile ECS is not supported by a recursive BIND.
So, let's say the recursive has 2 IPs, and they are in different views on the authoritative DNS of a certain domain. In this case, the 'query source' should be exactly the same as the IP which is the original's destination IP , so that the corresponding query could match the right view. Does that make sense?
