Hi all, I have a question related with the contacting external servers. 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.
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 Thanks in advance. Kind Regards, Luis
