Into a UDP response. A resolver will recieve the first 512 bytes of the truncated response and may then use TCP to get the complete response... unless there is a firewall blocking 53/tcp in the way. But how often does that happpen? The root servers sustaining the ensuing SYN flood is another issue. -- Crist J. Clark [email protected] Globalstar Communications (408) 933-4387
