Hi all,

Does anyone know what algorithm BIND uses to order the NS records in a DNS reply? e.g.

dig @66.6.49.217 NS yahoo.com
yahoo.com.              160275  IN      NS      ns6.yahoo.com.
yahoo.com.              160275  IN      NS      ns8.yahoo.com.
yahoo.com.              160275  IN      NS      ns1.yahoo.com.
yahoo.com.              160275  IN      NS      ns2.yahoo.com.
yahoo.com.              160275  IN      NS      ns3.yahoo.com.
yahoo.com.              160275  IN      NS      ns4.yahoo.com.
yahoo.com.              160275  IN      NS      ns5.yahoo.com.

Successive queries give different orderings of nameservers. I though it was decreasing RTT order, but wanted to confirm.

Thanks,

--Ricardo
