Re: referral doubt
Trying to resolve www.testing.server.com When contacting server.com nameserver I receive in the answer 3 NS and 1 A Additional record: testing.server.com NS ns1.testing.server.com testing.server.com NS ns2.testing.server.com testing.server.com NS ns3.testing.server.com ns1.testing.server.com A 192.123.123.23 In this case BIND9 should immediately send a subsequent query to 192.123.123.23.

What happens if the ns1.testing.server.comhttp://ns1.testing.server.com/A 192.123.123.23 doesn't responds? will it try to get the others? yes, if it's able to find out their IPs. -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.

If my server receives an referral answer from an external server with 3 NS records but just 1 A additional record, what is the normal behaviour? is the server supposed to resolve all 3 nameservers or continues with the iterative process contacting the server that have the additional A record. I don't know what's normal, but BIND9 should continue with the process with the server that has an address (while trying to resolve addresses of other NSes). For example: Trying to resolve www.testing.server.com When contacting server.com nameserver I receive in the answer 3 NS and 1 A Additional record: testing.server.com NS ns1.testing.server.com testing.server.com NS ns2.testing.server.com testing.server.com NS ns3.testing.server.com ns1.testing.server.com A 192.123.123.23 In this case BIND9 should immediately send a subsequent query to 192.123.123.23. --- JINMEI, Tatuya Internet Systems Consortium, Inc. ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
