Hello BIND ISC, We are testing a query: FQDN: test.testdomain.net Query Type: AAAA
Client > DNS A > DNS B Simplified DNS query flow: 1. Client queries test.testdomain.net -t AAAA 2. Query goes to DNS A which then forwards the query to DNS B 3. DNS B responds with 2 ORDERED IPV6 addresses to DNS A 4. DNS A receives the 2 ORDERED IPV6 addresses from DNS B Expected 5. DNS A responsds with 2 ORDERED IPV6 addresses to Client What is happening 5. DNS A responds with 2 NON-ORDERED IPV6 addresses to Client Things we have tried: Turn off cacheing on DNS A and DNS B Things we noticed: When the query goes from DNS A to DNS B, the transaction ID changes When DNS A responds with 2 IPV6 address to Client, the transaction ID changes back to the original transaction ID. What options/settings are we overlooking to make sure the Client receives fixed ordered query responses? What could be the reason for DNS A receiving the ordered query response from DNS B, but does not send the ordered query response back to the client? Thanks Brent D
